Would it be a good investment to put away $200 each paycheck for the next decade in spec-crypto currency?

Hello I I have begun to think about investing a little bit each paycheck. I want to invest in smaller cryptocurrencies such as Zcash, Dogecoin, and Monero every paycheck. I remember being a teen thinking I should do it with monero and I regret it a lot now since it was $50 at the time and now is $150. I only intend on investing on Bullish coins. I want to do $120ZEC $60XMR and $20DOGE. I intend on increasing or decreasing this amount as my pay sees fit. After this I intend on letting it sit for another 2 decades maybe 3 to grow. Bad idea for a young person?
