I invested a small amount in GMT coin today. It's up 182% this morning. The crypto, which was opened on Binance at $ 0.01, is currently at $ 0.23. Is there a future for this crypto or is it just a crypto?
It's good that you were able to get in before the huge pump, but the question is, is the run sustainable or not? Is this just part of the pump and dump by the project themselves or some entity behind to make money out of it?

Sell it before it will be dumped again. 
I would not be surprised to see this happens with a new coin on binance from binance IEO. It's always getting pumped after listing but for long term and yeah, you can take a look at some old tokens like TLM and many more. That looks like a promising token to hodl but it seems like you didn't aware with the crypto cycle. It will be dumped again once the hype will be done. You beat me to it, lol, but there is some truth on this advise. It's a new coin and then getting listed on the top platform. So there is this hype that's why the price suddenly shoot up. Maybe it will continue it's rise, but definitely a dump is incoming so just be ready when it happens. Or get out and take profits already and not to be greedy.
While he is in positive profit, better sell it. But if the OP is confident about its development and possible future, then hold. But if not, sell it while it is still in the 38cents now. It already went down from its ATH of of about 43 cents. I don't know why it was pumped but maybe because it is a new coin in Binance. Don't trust much in the market. Better get out while you are still in positive, that is, if you can't keep up with their progress.
