don't sell it right now, just hold it until the halving
Most users think the same way that halving gives a big increase, but none is sure of it. So the reality can be experienced only when we cross the days of halving.
Yes no one can be sure what will be the price at halving so fingers are crossed and hoping for the best price at the time of halving.
We all long to have a good profit after the halving, that is why we are slowly transferring our altcoins to bitcoins now.
For me I am very much positive that there will be a good news for us after the halving, we just need to trust bitcoins. In addiction, invest what you can afford to lose.
