Over the years I have noticed that most alt season started as follows:
1. $BTC pumps first.
2. $ETH $BET & $LTC coin pumps next, leading indicators of the Alt season.
3. Big marketcap tokens next. Usually top 20 on CMC.
4. Then full blown Alt season.
I have same experienced as starting my crypto life .I have noticed many ups and downs but at the end who hold their nerve with there asset got a huge return specially on alt .Now the same things are going to happen once again .We have see the pump from eth and hopefully alt rally will come soon .
