i bought bitcoin when it was for $14 k
now it's less than $4k. i lost +10k per one bitcoin.
Bitcoin is worst investment ever i could imagine.
it is your worst investment, not ours so don't blame the whole of us, have you heard the saying only invest what you can afford to lose, it has been preached thousands of times here so if you lost with that big amount it's because you did not sell when it's time to sell.
