Hate to be boring or negative even but if the plan is just to sell and everyone has a similar plan can you spot the flaw in the plan to this ever happening 

Forget personal perspective or bias on this for second, the market overall is only really going to go up with higher usage even if its just for value transfer.   Ultimately people criticise BTC for not having a greater purpose, an underlying usage such as the metals or various commodities have.   BTC has to be useful, thats the plan and its the only reason we can expect it to retain value over time is by providing a community of users that usage that is not as easily available elsewhere.

Its both simple and an ongoing challenge, I'm not certain on the outcome but BTC will need to develop as a product probably so the plan that works is unknown exactly
