0.2 BTC in hand.. One Altcoin to invest? Please share your thoughts.
I would suggest holding the BTC that you have now, because now is not the right time to invest in altcoin if indeed you need to invest then choose one of the top altcoins in CMC.
Good, meanwhile, he should not invest all his BTC on altcoins irrespective how high they might be in rank. Anything can happen. Sometimes, I even recommend that there should be something to fall back on, whenever the market plummets and that most ties should be stable coin. That will be of great help here.
