I think 2020 will be one of the best years for cryptoccurency. Cryptocurrency will be already well spread and regulated, people will have more faith in cryptocurrency.
I am also waiting for the miracle in 2020 because this year the Cryptocurrency market has not really grown and this makes many people feel depressed and are showing signs of leaving the market more. I personally only invested in Bitcoin because it was the safest investment in this period and it has helped me make a good profit in the last two years.
