Why not only save 1 btc there are still 6 btc left for your plan, but if I were you I will add it up to my savings and going to hold it until the halving
comes for sure I will get some profit on that amount and a good amount for sure.
Its good to hold all you bitcoins till the halving, if investment fails then you will loose your coins and will result in loss, I would simply prefer to hold till having without taking any risk.
it was quite good, if you do not want to take risks. but if I might take the risk and use some to trade, so when prices go up after halving. I could sell more than 10 bitcoin
If you have good knowledge and skills of trading then you can surely try it as trading is the best way to grow your coins, and if you earn profits then it will help you at the time of halving.
