My top five Altcoins I poured my investments into are Ethereum, Litecoin, Dash, SXDT and the last but not the least an under valued coin no other than Dogecoin. A lot of investors might underestimate Doge but I earn profit from it way back 2017. Well, for me it always depends on us what coins we are comfortable or we believe in with and it doesn't matter if they are new or old coins, what's important is that we love what we are doing but of course we need to make our own due diligence in choosing the right one.
