Thank you @muratkbesiroglu
We should not be afraid of investing in crypto currencies. We should know that crypto currencies are here to stay. Much as it's hard to make short term predictions , long term predictions are more reliable very useful in laying strategies.
I know that just like other assets that appreciate such as land, crypto currencies also to appreciate in value. One way of becoming wealthy , not rich , is by looking into the future ,investing in future technologies and make profits when the technology is adopted by the masses. Taking an example of e-commerce. Did you know that people who saw the e-commerce boom approaching invested in it while others took it lightly. Now they are the wealthy guys. Remember the founders of Amazon, eBay and Alibaba.

So back to crypto currency prediction. Let's not make short term predictions but let's opt for longer term predictions. Remember how the bitcoin started and people didn't expect it to be so important. Those who saw the opportunity took advantage of it and bought some bitcoin and as you are aware recently when the bitcoin reached $20000 they became wealthy.
