Hi, many people are still complaining how many ICOs ended up as a scam.
The cryptocurrency idea is to create a free worldwide decentralized ecosystem. Free for all, for honest but also for dishonest people. It is free market and you should protect yourself before losing your money. You don´t like it? Then you do not understand crypto.
We cannot really avoid such circumstances since ICOs are created with freedom in it. The best thing we can do about it is to be responsible on finding which ICO to trust. Make sure you read the whitepaper and view the history of those people running the ICO so that you can make sure that it is credible enough to trust.
