Yes, like others said. be careful with ICO.. Make sure the development team is real and has previous development background, not just trying to come in for a pump and dump. They need a real purpose behind the coin and a real pathway for success. Many just have whitepaper and theory but no actual product yet. With that said there are still many profitable icos. Some of these free airdrops are even turning profit and possible future potential. Crypto evolution is always impressing.
