An ICO without legitimate escrows always turned into a scam. Scammers hate escrows, they will do everything in their power to avoid them as much as possible. Before investing make sure the ICO coin is using trusted escrow service.
exactly this is the first thing i look when i joined ico i making it sure that the escrow that will handled my money / btc is one of the trusted escrow here because they are taking care of their names it will hard for scammers to fool them.
even escrow will holding the money when the time ICO is running you cannot still make sure that the ICO project will not turn scam since this coin will be easily dumped by the devs once it will be added on the exchangers and it got huge buys and got also huge btc volumes, and we surely see that one's and those coins are moslty located at yobit exchange, and also thats the reason why we can't trust fully the ICO coins since they are prone to became a scamcoin when the right volume and time comes.
That's why when someone want to put some decent amount on those coins on ICO, remember that manipulation can happen anytime or even every minute/s since it's easy for whales to change the phase of the price that's why monitoring is really a must. We should act fast here.
Also remember to get out when people already sees some sure profit rather than being a greed one waiting for more pump and price increase to avoid regrets.
