2019 had been not so good for altcoins as this year has given us number scam projects and as a result, some of the genuine projects have been failed wherein people just pretended any projects with ICO as a scam. I think 2020 will bring new hopes and some good project in the market by considering 2019 as a learning area.
Every year in the past 10 years has provided some scam projects, including 2019, nothing changed.
It will continue to happen with fraud that continues to grow every day. Who knows how long this will end and see people happy with what they have done.
