If I have 10 btc then I will go with altcoin trading as at a moment altcoin market is very hot and there are some really potential coins which can give me quick profits.
You are right that invest that amount on trade because i also recommend that trade is good way to earn big profit there is very popular for earning more bitcoin and its really you can get quick profit .
I agree, I have been making a decent amount of profit from trading, especially trading altcoins in the past year. it is a little bit risky business but in time you can get to learning it and making profit consistently.
and in altcoin markets there is always some opportunity or another to take advantage of and make some profit from your investment, like in the past two days with monero and the big pump which has not yet stopped.
