Honestly speaking yes crypto has still lot of potential in it. Especially if someone is targeting it for a longer period.
But is it the right time for investment we cant say any thing about it. Because it can go further down or it may show a bull run here as shown in last 2days. but any thing is possible.
But if we want to earn we have to take risks. I'm not an expert but In my opinion we can invest because
It seems that prices are at the lower side and eventually will go up if invested for the longer period. The point here is one should invest only that much of amount which he can afford to hold for a longer period.
If someone is will for short term, he should have proper market research before entering into some coins. It is also advisable to have some analytical tools available in the market to form an opinion.
Another point where many of us make a mistake is that one should not invest all the money in one coin instead invest should be diversified.
One should not make all the investment at once in one time instead investment should be made in steps.
