To be able to answer this question, you should first analyze the existing cryptocurrency. The analysis can be in the form of fundamental analysis (related to news of cryptocurrency development) or through technical analysis on the price of bitcoin, ehtereum, litecoin, etc.
If you do not objectively analyze and only follow gossip or suggestions from other people then I suggest not investing in cryptocurrency because of course even if the price of the cryptocurrency increases, you cannot estimate which cryptocurrency will meet your expectations unless you have conduct analysis both fundamentally and technically that can support these suggestions.
Wise in investing is the main key to your success and the wisest attitude in investing is that you do your own analysis of risk and profitability. That's because only you know for certain about your finances as well as the conditions you are facing.
