How about this novel idea. It is actually a proven system that works!

Print up 2 billion tethers. Put tethers to work buying bitcoin non-stop. When there is less than 10% tethers remaining in the purse then start selling the BTC off. The buying frenzy will absorb much of the BTC sales. When all of the BTC has been sold off you should be left with a price at least double the previous low.

Then repeat every 2-3 years. Happy trading.
