Thank you guys for your inputs!
I think Binance its a good option for me, because I buy my TRX there with ETH.
But once I have lets say 5,000 TRX, that I bought at 0.04 and the coin gets to 0.8... is it wise to then trade them back to ETH?
Will I really get any profits doing so?
Of course you'll already profited by ×20 from your capital and with that significant amount will give you a decent profit. How I wish trx will be that price!

I can say that I bought trx half way, in short I bought when I thought it's the bottom but to my surprise it just go more dip. Anyway, I'm a long term holder so nothing to worry, I guess.
