Investing in IEO of a famous exchange is the safest investment however, due to a lot of entries and competitions, you will only get very little amount of those IEO tokens.
Everyone wants their investment to be safe. And if IEO is in Binance launchpad, then I think it will be the safest investment. So the competition here will be a little more, that's normal. Almost all of the projects that have IEO in Binance are successful projects. As a result, there is no need to worry about whether their tokens will be sold. This is why the amount of tokens is reduced individually.
