The best strategy is buying now and never sell it until the price going to $10000. You can't think the price is only $200+, right?
It might happen then you really never sell then. So you have nothing from your investment.
On other hand you can earn from bitcoin price movements.
This 10'000$ dream is cool, problem is you have no way of knowing if it will ever get there. I'm not saying it cannot/won't, but do you know for
sure that it will? Otherwise you will be sitting on a bunch of coins, not doing anything with them, just to find out that in 10 years it is worth the same.
