ICO were crazy in the first few years, but there were also a lot of deceptions. Many people have participated in ICO but their money has been scammed.
Many ways now are to get a whitelist to buy low-priced altcoins, which is good for publicity and will not be deceived.
In the past, there were not many choices that could make people luckier because Scammers always took advantage of popular fields and land such as ICOs, but for now every investor already has many options to get profits and also good things for themselves each of them.
