This might be real.
Or this might be a speculative bubble.
I can't tell

I have 3 BTC that i bought below 55.
If I sell now, and the price comes crashing down, I could end up with 5, maybe even 6 BTC!
But will it?
If you need fiat then sell. If not then keep. I suspect your life would not crash if you kept 3BTC in your wallet?
