I can tell you this, hex will be assigned a satoshi value, it will likely rise as BTC hits ATHs and drop as BTC his ATLs as ALL altcoins do. I can guarantee you that hex will be worth less at BTC ATLs than it will be at BTC ATHs.
Might be a stupid question but I can't work this one out. Some exchanges are offering certain cryptos almost 15% lower than the more recognised exchanges (e.g. Binance, Bittrex etc.)... Would it be possible to just buy cheap from the lesser known exchanges and just transfer it over to Binance for example?
