On August 1st, they will implement the Segwit and there are some uncertainties involved. If I were wanting to invest, should I do it before or after the date?
My concern is that the price would still be higher than the price on August 2nd if the implementation did not go as smooth as planned and caused the price to drop.
What do you want? Buy at the current price rate and wait after August 1 for results or just watching it without any coins on hold. Play gamble mate as you are just trading where losing is normal. What if the price explode to the moon after August 1? It's still better to have coins on hand since you still sell it after August 1.
Like I said, play gamble and take the risk. It's no different from doing trades where you coins on hold to be dump.
