Ready for the Bull Season ?

Bittrex, Poloniex and Crytopia markets delisted more than 300 coins in total, during the previous months.Delisted altcoins are the coins that made ATH(All Time High) and showed 90-95% decline in Bull season.
They lost their trend.
Because, even the tulip balloon made ATH just for one time and this situation was a financial loss for millions of people.
So, what were the reasons that led markets to delisting?
1-)These markets are altcoin markets and for that reason, their capacity has fallen a lot, during this bear season we are in.Maybe, we can consider this as a reducement of altcoin amounts for the new investors and this has 10% probability.
2-)They think that the bear season is over and prepare for the bull season.Because there are hundreds for altcoins that never made ATH or got shilled. Where? Of course, they are in token junk heaps like IDEX.
Markets are getting ready for the bull season. How about you?
