Stay off Deribit, i had a bad experience although got all i put in back... I had a bad experience although recouped all with Mortontech.org legal stand off against Deribit dubious ways with actions on my case, keep off clear with any of the reps, they are swindlers and will leave you with nothing left then lock you out and ignore you, Deribit is fraudulent in dealings, did you see any of those harassment coming? no, i was constantly hounded to put in more, the moment i asked for profits payout I was served with a fee and after I complied, they pulled a fast one by ignoring me totally, they manipulated me the whole time with promises all to be ignored and not get nothing safe for the swift action I took with Mortontech.org , all I put in Deribit would have gone.
