Well this is probably a better way to have an investment by just holding your btc. And 1 btc is enough for that investment. By just holding it
after the end of the year you will sure get a benefit because higher chance of increasing of btc's price.
But if you want to make the most out of the price increase, you should not be contented in holding just 1 btc. You should be holding more, everything you can afford. Halving is just a few months away, so holding is. Good choice.
Yeah and don't miss any opportunity to collect as much as you can before the halving, as more coins will allow you to make higher profits at the halving.
