The best advice for cryptocurrency and forex traders is to only deal with well known and respectable originations, especially when it comes to selling your assets. It saves you the hassle and you are very much guaranteed your money or the agreed amount in the case something goes wrong. If you are lured by the seduction of insane amounts on returns of your investment then the chances are you have fallen for a scam. I see a lot of these multiply your investments in minutes on instagram and I truly feel sorry for the gullible people who go for it. Don't get me wrong I'm sure they are some reputable traders on instagram but I see a lot more scammers than legitimate traders on there.
