Cryptocurrencies are in a bear market for a while (since January this year to be exact) and now is the best time to buy any of them. It’s a little contrary to what most people do especially if they risked too much in hope to become rich quick and when it didn't go as they wished then panic started and sold most if not all for a loss. If You are an intelligent investor and risk what you can lose this market is great for a shopping spree, you get everything at discount.
BTC is a little over 6k and could go lower (I expect it to reach 5k area, so we have double bottom. From there it’s a good chance to recover if not even 1k is on the line), but this doesn’t matter much if you are using cost average strategy.
You may ask what is cost averaging? Well, It’s an investment strategy when you buy a fixed amount of a particular investment on a regular schedule, regardless of the share price. The investor purchases more shares or in our case altcoins when prices are low and fewer shares/altcoins when prices are high. For example if you have 1k to invest you can divide it into 10 equal pieces and invest when a good buy opportunity arises. Each time you see a correction you can buy 100$ worth of altcoins and so on. Even if the market is rising, you wait for a little retracement and buy another 100$ worth of altcoins. You can see how it looks in practice in picture below. Each time a good buying opportunity happens we can invest our fixed amount and spread the risk (I used arrows to show the buy entry). In this example you can see that in the long term we are in a nice profit. We don’t have to be perfect with the buying entry. When we see a stronger retracement we invest our fixed amount. 
And now with falling market it’s good time to accumulate good altcoins. One of them that has great potential is Adelphoi (ADL).
I’ve been looking at ADL for a while and their team is one of most active in crypto scene. They have weekly updates and recently the progress is showing. Few months ago they were added to Livecoin, which brings more liquidity as it has about 30 million of daily trading volume. However the volume on ADL is small, but this is OK because we want to accumulate them. The price mingles between 0.04$ and 0.07$ per ADL. It’s still more than what would you get if you participated in ICO, but not by much, so it’s a good buying opportunity now.
The reason I think this altcoin is good is that they are undervalued by far!!! And I mean by a lot, because they have a lot of projects coming out later this year. One of them is iFin which is a DEX (decentralised exchange) it will bring liquidity of centralised exchanges and all the professional trading platform we want. 
They will offer spot, forward (futures) and binary trading. The whole technology and the future of DEX will only grow on popularity and they will be one of the first DEX if not the first one with such technology. You can find more about iFin at https://www.ifin.io
Just this alone is huge potential for growth and not only that, but ADL is basically a crypto Kickstarter, they have several projects in pipeline that you can invest through their community. I can say they are even better than Kickstarter, because in Kickstarter once you raise funds you are left all alone. No help, nobody will advise you, while with ADL you get the whole community. They bring investors and workers and idea founders together.
If you are good at programming, marketing, designing, leading, accounting… you can join the project and be a part of the core team. If you are looking where to invest, you can search for a project you like and invest in it to receive profit participation once the idea is realised and profitable. If you have a good idea, but don’t know how to start you can submit one at ADL community portal and get a feedback from the ADL community.
The next project I like within ADL is Siesta Cloud which will disrupt the travel industry. Now we are left only with aribnb or booking, which are centralised and don’t offer nothing else except location, reviews and price filtering. Siesta will offer a tailor made vacation. No more endless reading of hotel reviews and piles of information just to select a perfect vacation. I like to travel and I’m really looking forward to use their platform. You can find more about them at https://siesta.cloud/
I could go on and on about ADL, but with information I just described, we can clearly see how undervalued ADL is. Now in bear market it’s a perfect time to accumulate them, because once projects come to life and start generating profit the price will skyrocket.
