@op you can invest your bitcoin on ico's becauase ico's are the most promising investments on this current year . you can earn a big bonus and perks when you invest as early as possible , plus you can sell you shares at the end of their project to earn again a huge profit .
You should remember that during the last 4-5 months, more than 95% of the ICOs either failed at the time of listing or they turned out to be scams. If you think that they will go up in the future, then go ahead and invest in them. But I would rather avoid them at this point of time.
ICO investments are good provided you invest in the right coins. ICO Coins can be very profitable because you get the coin in very cheap price and once it hit the exchange it can be really profitable.
