Why not the local bottoms? The best dates for DCA-ing BTC are between 15-18 every month.

And I have tested this theory out, at least as a cosplay (wish i did it in real life.) We say trading is bad, "Don't trade, just HODL". Which is all well and good, except by using my Monthly "Salary-Bills-Bills-Bills" insight (i.e. people get paid at the beginning/end of the month and have disposable income, while they get piled on with bills bills bills and have no disposable income at the middle of the month, so BTC price does not "follow the moon", isn't "to the moon", but instead "follows the money", and it goes up at the end/start of every month and goes down at the middle of EVERY month.
Buy HODL trading 1 BTC in and out of USDT since 2015, any average trader could have turned it into 30.25 BTC today. No kidding.
Here's the hypothetical (but very realistic) Trader cosplay in Google Doc: https://docs.google.com/document/d/1H3Z8Aq_ItFRh6PrGn_V4MVmZxIHksZTObjt9ztFWAZQ/edit?usp=sharing
And here's the screenshot of how i worked it out in a spreadsheet. Though the result of the spreadsheet (where ALL local tops and local bottoms are hit) says 1 BTC in 2015 would turn in 386000 BTC today. Which is impossible, since it wouldn't be possible to convert even 5000 BTC to USDT even on a big exchange like Binance. So after a point in this scenario, it becomes impossible to convert an obscenely large growing pile of BTC. But theoritically 1 BTC does turn in 380,000 (386k yes) BTC in 9 years if you convert to USDT at the start of the month and convert back to BTC at the middle of the month, accurately, every time.

MWAHAHAHAHAHA (evil laugh) MWAHAHAHAHAH
I have zeroed in on the exact date to convert to USDT and exact date to buy back BTC every month. I calculated for 1 BTC starting in August 2018 till Jan 2023.
1 BTC became 15 BTC.
MWAHAHAHAHAHA (evil laugh) MWAHAHAHAHAH
I'm now researching "How to build a BTC trading Bot" on Cryptomaton.
This is going to be spicy. I'll do it even if i lose my disposable BTC balance. I will report back here in 5 years.
