Its very important that people hold some bitcoins in their wallet, even if youre a day trader you still have to keep some coins in your Bitcoin wallet and any other coins you would like to save because at times the biggest profit might come from long term Hodl. We dont really know how the situation might be after the Halving, there is no assurance that the same thing that happened in the past, the bull runs, will repeat itself this time around.
I have seen a lot of technical analysis and the price seems to be moving the same direction and I strongly there will be a bull run after the next Halving. I have invested an amount according to my level of risk and Im waiting for it.
