prices are always fluctuating in the crypto market, it's normal and part of the entire ecosystem. It's rather strange for most new joiners and not as they would usually expect, they see these huge fluctuations and their assets are one day -20 and the other +60%.. but that's quite common and it's due to the low market capitalization these coins have. Don't let this deter you or be a reason for not investing into altcoins, because altcoins offer some of the best returns out there in our current financial system. The only way you can make more profit is probably by creating your own company and trying to do what they are doing, but besides that it's a great way to invest for some short and even long-term gains.
