Seeing this many new people entered in the market and earned good amount of money by supporting ICOs.
this is the problem right in the middle of your comment!
and I don't know how, you knowing this already, are using the words "supporting" each other!!!
the problem is that these days all the newcomers are only interested in making money from cryptocurrencies. they see bitcoin and think they have missed out, then they also see the
advertisement of all these useless tokens which are promising them big returns so they start pouring their money in their pockets. in the end we end up with a bloated altcoin market which is in a gigantic bubble and its burst is actually taking bitcoin down a little too!
