I think today's drop is still mostly driven by problems on the Cryptopia exchange.  People can't get them out for the airdrop because of problem, so they just sell, and that drives it down.

Airdrop doesn't end for estimated 8 more drops - BTX held in wallets will increase by 78% over that time.

I also think some BTX holders think BTC is about to explode, so they are buying bitcoin.  I think it is very hard to beat a guaranteed 78% return in 2 months.  BTC will have to be almost 20k by end of April to match, and that is if BTX does not go back up to the mean of it's price range - around $25.  I really kicked myself for not buying last time BTX went down under $18 - won't make that mistake again.

Buying low and holding.  Only silly people sell BTX.
