I wonder how many coins they still have to dump? it's crazy... wtf? why it's still dumping and dumping...

Last week I had 7BTC now I have almost 1,5   

WTF is going on? I can't understand. some days ago low rises, than suddenly big drop in a minute! than again slow rise looks like everything goes back on truck and now BUM dump! it's insane! I will crazy !!!   2 days ago I've had 7BTC now I have 1,5   I'm starting to regret these days when I decided to invest in crypto, to much lose and any profits
