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?
So sent the money to accelerate - to BTC.com - got spam email - they basically have said the are ripping me off. This is very frustrating. I will advise anyone who is not using crypto to never use it as there is legitimately no recourse or support. Very frustrating.
