Okay 10 days hold ? I would never use such things the price would ofcourse fluctuate and then you would need to consider +/- this is not how trading works.
Honestly there are people doing p2p in person !
Yes but p2p online is much higher risk.
yes, 10 days hold with coinbase really sucks. But at least you can withdraw back to bank account after 1-2 days in my case, but only with the high transfer fees of 1.5%.
