I am sure that blockchain and cryptocurrency are two big trends that can be staying for good into the future. What is happening right now is that because of the immense potential and virtually global reach of the cryptocurrency marketplace, there are many projects and platforms taking advantage of the greed of the people.
Plus, of course, since this is just a young industry, we can expect many failed start-up projects along the way. Sadly, there is nothing concrete we can do on scams, frauds, and failures except to educate people, so they know the risks they are entering, and they can do the vetting process themselves -- and hopefully not be blinded by the possible gains only to realize they are already holding empty bags or should I say worthless tokens and coins.
