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.
It seems that price won't up high again after $14k had reaches on the market and keep falling. It is worst investment and feel sorry to you but still you can hold and wait for the recovery. If you choose to sell now you lose big amount so it is more worth to patiently wait. Not only experiencing this but still keep believing on the potential of the coin.
