Its a good idea though. But it would have been better if you divide the total funds in a ratio of say 8:2 so that you can save about 80% in stable coins while keeping de remaining 20% in a volatile coin, probably BTC so that your funds can appreciate small by the time you are withdrawing your funds
I would advice you to put it into bitcoin because of its foreseeable longterm profit but sincerely speaking the investment window of 6months which you gave is quite short. 6-8 months ago and bitcoin was trading under $4k. The market is too volatile to say the price of btc in the next 6months. You might have to wait a bit longer for gains
