Can someone tell me how low the price of the bitcoins will go .
it is impossible to tell because there is nothing right about this drop anymore, so you have to wait and see when the market makers decide it is enough dumping and where the decided final bottom is.
Is it worth to make an investment or should i wait ??
if you have not made an investment yet then waiting is the best option. and you should be happy because now you can buy a lot more bitcoin than you could if market was acting natural.
