Good way to grow it is to be an active investor or a trader, you start with a small amount of money so you need to be very aggressive if you want your money to take you further, there are a lot of players in the community where were able to manage to grow their money in a short period of time so I believe you can if you choose the best method to generate money.
An investor does not need to be active in the case he is dealing with bitcoins. But continuous monitoring and updating knowledge on bitcoin related stuff are always recommended.
$50 must be a perfect amount to get into crypto world but it would have bought double the benefits if OP decided to act some 6 months back itself. But buying some bitcoins and saving them in cold storage for few years are the thing I prefer to do if I were the OP.
I do not want to get struck with altcoin trading with only $50 capital. It's a small amount when it comes to trading, you might need a larger amount and a lot of knowledge behind it or else you're just wasting your 50$. You should work and earn more when you're going to trading or at the meantime buy btc worth of 50$.
Just put it in bitcoin. No other investment is this safe as for now. You definitely gonna earn a good return by the end of this year. I agree amount is not that much. But still you can grow it best with bitcoin.
True. BTC is the best bet in that amount, when I was just starting, I've bought about 100 plus dollars BTC and I'm happy that through time it go bigger and bigger when you convert it to fiat.
