This is a fully automatic cashapp to bitcoin converter site. Transactions complete in less than 15 seconds once payment is sent so feel free to exchange small amounts to see how it works first. Percent - I have a tier system so depending on how many trades you make your trade fee goes down. Its 5-10%. The site also trades other things like ETH/ETC/BTC. You can trade any of these in any direction (ETH -> BTC // ETC -> ETH // etc) https://coincastors.com
