why now all coins are going down and when are they are are going to stable ..any idea pls help me
are falling because of the pressure of the governments and central banks of many countries, I believe that you read the news every day, in some countries governments are adopting very tough stances against bitcoin and this is reducing the demand
because i have invested around 100000USD into crypto in last year
Okay, this is really a lot of money, but you should not sell in any way. Hold your currency for at least 2 or even 3 years you will have huge profits. But I hope you have not bought some useless altcoin, because a useless altcoin will only bring you huge losses
