If you believe more in BTG, then try to convert your BTG to NxT for the airdrop, then exchange back to NXT if you want. But in my opinion, NXT has a good potential and just holding it will give you lots of coins. ARDOR is also a coin which was given to the people who had NXT and now the price of ARDOR is 10k sats. more than 1.5$

Hmm its hard. Because with BCH I sold too early and lost a lot of profit.. I did half half to have double chances :D
