If I were you, will think 100 time to invest in low volume coin, Moreover Zerocoin is a privacy coin that has been abandoned by investor. I won't keep money on a coin like this for a long time (2 years), because I think there are still many other coin that can still profit me.
If he wants to invest in the cheap coin, he should look at ADA, TRX, Matic, or ALGO and other coins because I think those coins will have the time to increase. Besides that, those coins are at the top of the 50 coins list, so the chance to increase will be wide open, especially for two years. After you have one of those coins, you can stake it for two years to earn some amounts that can help you increase the amount in the next two years.
