Well bitcoins has reached $10k which is amazing even for bitcoins.But to invest in bitcoins now would be very risky as bitcoins prices can drop or even can rise no one is sure so i would recommend to wait for drop on prices because there could be correction where prices may fall.Bitcoins maybe reach $15k or can drop by end of this year so whether to invest or not is very hard choice.Buying at cheaper rates is always the good investment so try aiming to buy at drop.
