TRX is a very good altcoin, currently I also hold TRX. because waiting for the high price. and it's very real to make a profit. before that I've been trading TRX for 3x and all got a good profit. and right now I choose to hold and invest long-term
You may be right, but investing in one coin only is still vary bad move. It is not worth the risk in my opinion and I would always suggest to diversify the investments.
