@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.
Sure, we cannot say all ICOs will end up the drain and even though we might have seen the bear market affect a whole lot of them over these few months when listed on the market, does not mean they will still not have a chance.
However, based on what pinoyden said, you really do not necessarily have to invest in ICOs before you are considered an investor, bitcoin is not a stable currency and it is always bound to increase in value as well over time, and that also makes it an investment option.
No one is simply saying that you're that investor when you invest in ICO, well people might even call it opposite since ICOs were mostly failing now and getting your appropriate from it is like a dream now to happen. It doesn't matter where you invest, just when you do it and then call yourself now a proud investor (for how long though?
)
