Most of people think btc will go further down so whats the big deal it will always recover and even you buy bitcoin now or later it doensot matter because with bitcoin going down all prices of coins go down so for example bitcoin was 20000dollars and you want to buy ethereum it was 1200 dollars now bitcoin is 10000 so ethereum went further down its now 650dollars so its up to you you buy now or later you have to get btc to get any other coin
