$700 will reach just in a few days, but I think we have to wait for the halving and at that time the price will increase to a higher value and at that tme you have to sell them.
It can be reached today because it is only a $20 difference. About the topic i think that it is not the right moment to sell everything for bitcoin. I would not risk so much because as we saw in the recent days the bitcoin price can crash suddenly. It is not a bad time to invest now in bitcoin but before few days it was better.
Yeah price was good to buy few days back, but now price is going up, so we should not sell coins now as it will be much higher at the time of halving.
It is a time that it is risky to sell and is risky to buy even though the halving is very near(few weeks remaining), so i prefer more to not do anything and hold them for a while maybe until after the halving or until the end of this year because i hope people will not sell their coins less than $1k.
If you don't buy then how can you make profit from nothing!? I think that the time to buy is always but this time don't know things are not going well, the halving is not taking this effect now as we expected to happen but let's hope later.
Price is low in compare to yesterday so I think this is still a good price to buy some coins and hold for the halving as it is expected that price will be higher at halving.
