Digital currency(also named: Cryptocurrency) are digital assets decentralized to save people from banks and government regulations. You can start investing through Netcoins, Binomo, Binance, or PointPay.
Cryptocurrencies have the purpose of saving the financial freedom avoiding government regulation and laws against the investors, you can start to invest today by many different Exchanges. like: Netcoins, Binomo, Binance, etc. I highly recommend to start with Bitcoin, the price is always rising and in the future probably will be adopted like a global currency in many countries accross the globe.
The purpose of cryptocurrencies is not earning some amount of money through short-term,in stead of just waiting for fast money without risk(day trader thinking) try to make your investm ents in cryptocurrencies with strong logical thinking reading some articles(websites to read: Netcoins, CoinDesk, etc) try to make hard work during the process, and you will see your future better than today.
You can start your investments through the following cryptocurrencies:
First position-Bitcoin(BTC): It's the best cryptocurrency no matter your level of knowledge; some investors predict more than 100K to Bitcoin in December; try to make your first investments through trusted Exchanges(examples: Netcoins and Binomo).
Second position-Ethereum: Ethereum is following the same steps as Bitcoin; you can earn Ethereum token(ETH) through investments(make a google researching about it) and selling some NFT(non-fungible token) through OpenSeas or another Nft marketplace.
Third position-Tether USDT: Some people are saying that this is the natural rival of Bitcoin because Tether USDT is a stablecoin with the same price as the American dollar; this probably will be adopted for El Salvador and Cuba very soon.
Fourth position-USD Coin: The exact purpose of Tether USDT, you can make a good portfolio with the cryptocurrencies mentioned before.
Fifth position-Cardano(ADA): This is a promise to start your investments and build a diversified portfolio; today's value is $10.
Sixth position-Bitcoin Gold: Another good stablecoin with the same gold price; why not building your portfolio thinking in the valorization of gold?
Seventh position-Tether Gold(XAUT): Another great stablecoin of gold, try to make it simple and choose your favourite between the sixth and seventh position.
Eighth position-Bitcoin Cash: A promising cryptocurrency with transactions faster than Bitcoin, I highly recommend reading some articles about it.
Ninetieth position-Polygon(Matic): During the first semester, this was the best to make some good valorization rising 6.394,44%, only changing the marketing strategy.
Tenth position-Pancakeswap(CAKE): Download Trust Wallet into your android phone and connect Binance account; you can change some cryptocurrencies and earn much more through this method.
Eleventh position-Binance Coin(Bnb): The official cryptocurrency from Binance, you can make transactions through Binance Coin and receive some discounts. Twelfth position-PointPay(PXP): This is the official cryptocurrency from the ''crypto-bank'' named: PointPay, which constantly raises the price; you will make a lot of money through this token.
Thirteenth position-Litecoin(LTC): Some investors say this cryptocurrency is the ''digital sliver''. This cryptocurrency is better for daily transactions. Like the last cryptocurrencies in this list will make a good impact in the future.
Fourteenth position-Ripple(XRP): Some investors are telling good benefits about the lesser-known cryptocurrencies; in my opinion, you can invest in all the other options listed above to build your portfolio in lesser-known options available.
Fifteenth position-KAVA: Another lesser-known cryptocurrency you can invest and earning a lot into your digital wallet.
Sixteenth position-Alien Worlds(TLM): You can invest through this cryptocurrency through Binance, HitBTC, etc.
Seventeenth position-Swipe(SXP): I think the only reason you will invest in this cryptocurrency is earning a small amount of money; if you're a millionaire, go ahead!
Eighteenth position-Vertcoin: Incredible developers; unfortunately, this is just another shitcoin without any future.
Nineteenth position-Dogecoin(DOGE): I don't like this cryptocurrency; it's a shitcoin, so I don't recommend it for beginners; however(I think you need to make some investments through this shitcoin after earning some considerable amount of money through the last cryptocurrencies mentioned before) if you are a millionaire or billionaire or have nothing better to do, maybe you will like it.
Twentieth position- Shiba Inu: Yes, unfortunately, worse than Dogecoin, only a cryptocurrency based in the last one, avoid this one it's another shitcoin.
Conclusion: You will really need to have some money to use Bitcoin, or another cryptocurrency!
However, the point is not how much money you have to use in your bitcoins, the real question is: ''Do you have a good knowledge about what you will do, and how to achieve your goals thr ough cryptocurrencies?''
Use your critical thinking to realize what is best to do in every situation; however a good strategy is holding your bitcoins until the end of the year some investor are predicting Bitcoin reaching 100K until december.
