Sorry Cryptodiscuss
but it's impossible to:
If you buy btx before airdrops
just because BTX start from two airdrops (to BTC wallets).
If you mean 'start to buy in first airdrop's time'... it depends.
Someone bought at $40. Period
yes and others bought at $20, and some at $5 and others still at .75....and some just mined and only spent on electricity ..so whats your point?
