No need for that plan to take effect in December.
We don't know what will be the trend for that month. You can actually take effect and deploy that plan now as we speak.
For a test strategy, you can have some small trades starting now and see what will be the result.
You have a point mate, everybody are very optimistic that the month of December is the most awaited month for crypto, but I think a back up plan it is still needed if ever the market by next month still didn't show good. We really don't know what will be the trend by next month and the unexpected price correction for Bitcoin and Eth are now taking place, and yet we didn't know when will it going to pump again, but yeah you're right this time is quite a perfect time to add asset to fill in our bags instead, in my case I have already fill my bags with Eth and Btc and now I am just waiting for a new ATH, hopefully.
