Investing 5btc on an altcoin alone is freaking too much ,if I have 5btc I would diversify it in many altcoins ,infact if that 5btc goes on bch only you would be upthreading in profits
OP is just too late. He should have dumped it when the market starts. I bet he received a lot of discounts enough to consider profit from being an investor but he missed it. 5BTC would have been enough for him to profit about 1BTC for it. The project is actually great, it had been compared to big projects like Zilliqa which is also another type but then of course Quarkchain were hyped much as to expect rise right after the mainnet.
