It's a very different environment now than it was when you asked，i might be would say investing in ICOS at that time，but now my answer besides BTC，it is still BTC，definitely not ICOS.
Many projects that cannot be trusted make ICOs unprofitable anymore...
even though it has high price volatility Bitcoin will always give you a profit depending on what price you buy or sell. even at times like this, you can still profit from Bitcoin by becoming a scalper.
