Cryptobo.com is a HOAX, stay away from it!
1.- Where they get the Bitcoin price and the market movements is an absolute mystery (there is no Order Book).
2.- The 500 satoshis is just a bait, I'm not new to binary options, the first day I opened my account turned those 500 sats into 3,500 sats within 3 hours, thought this was a fair exchange, after doing the first deposit everything changed, been trading different days at different times over almost two month, sometimes have left days in between sessions just to calm down, but their scheme is always the same, the price changes against you the last fraction of second, making you lose by a few cents, and then goes back to its regular trend, I've seen this too many times, the price going backwards even more than $30 in the last second just a fraction of the time, and this violent "corrections" are not supported on any other exchange neither Bittrex, Poloniex, Bitfinex nor Bithumb (yes, I'm a trader and keep my eyes on several exchanges at the same time).
3.- Cryptobo.com besides working with a 20% advantage (nothing out of the usual for binary options on any exchange), the algorithm lets you win one or two trades in a row, to avoid being so obvious, then it steal from you the next few trades with their unbelievable "flash market corrections" system, making it almost impossible to recover the losses.
4.- Besides a few clowns who showed up on YouTube showing off their profits on Cryptobo.com, promoting the site and attracting naive people to this hoax, every other experience I have found online are like mine and ramzaboy, don't believe me? do your homework or giveaway your money.
Hope this post helps as many people as possible.
Peace!
