I was a bit curious about "bitstrike" - but for the others - you would say they can actually deliver?
only they can speed up transactions for a fee, everything else is mostly fraudulent sites
Very hard to use - I have to send an exact amount to the BTC.com address (in Bitcoin Cash) and if not they will reject it - but coinbase takes a fee and won't let me calculate that in the transactions so its basically impossible. Extremely frustrating and Coinbase will not return any communication so essentially my money is stuck somewhere forever?
Why don't you install a bitcoin cash wallet on your PC or smartphone, send your coins there, then have real control ? That's what cryptos are about, having control, not giving it to third parties.
