this will be another depressed year for the most crypto projects. I will not surprise if some of top 100 currencies will collapse in 2019.
Most probably, you will be proven wrong. Definitely this year will not be that much struggling like we had in 2018. It may be boring year for the people who are all looking for exciting rising markets but for long term holders there will be no big differences from last year.
I am expecting crypto may bounce back this year sharply. Most cryptos will have new ATH and like you mentioned top 100 coins will not be a big concern when they will be failing or even get collapsed too.
You are right. It is always expected to have drastic changes in top 100 coins. No wonders if wee see multiple coins will be losing their ranks from top 100 in coinmarketcap list. But, I am sure that bitcoin and few other major coins will never lose their reputation and ranking for sure and they may grow further in this year too.
2019 year will be crucial even have passed half of its first month, bitcoin is not showing where it will be heading. I guess we may get good sign before the second quarter will start. In between time, this market may be boring as most of the coins will be showing only sideways movement alone.
