how can a big pump leading to a big bubble be a good thing? and trust me, you won't make profit from it because when price of anything is going up like that you will always think there will be more so you will wait for 2000,3000,10000.... and don't sell and prices like these don't last long and before you know it price drops back down to $600 (in case such pump happens)
Let's be realistic if the price pumped to $10,000 it would not fall all the way back to 600
In that event, 600 would be a memory, just like buying a bitcoin for under $10 is now for us....
It would really be a dream if bitcoins price would reach 10k price but as you said if we reach that amount it would not really dump its price back on 600 which is impossible thing to do unless if all bitcoin holders and investors would dump their coins for sure it would go back to its price point.
