Hi,

I would say it's a really good question for which I thought a lot...

My conclusion and personnal advice is :

- if you really believe in BTC, don't look a the current price and start to buy now.
- then, as there will be some big drops in the price as it already occured, then continue to buy at these special moments.
- for the "targets price" : I think for sure you have to put some of your BTCs (30, 40 , 50%) on paper wallet or hardware device and FORGET THEM FOR AT LEAST  7-8 years...
- for the others BTCs, you may think and try to sell either at pics (very very difficult) or more likely after several goals reached by BTCs...

Really the most difficult part will be to forget some of your BTCs while following the BTCs price and continuing buying or selling sometimes...That's why I would suggest paper wallets for a fixed amount and then for only this amount you forget them for a loooong time...

I'll also say that of course nobody can predict the future price of BTC BUT either for sure it's far from its real value :
in 7-8 years either it will be at 0$, either it will be over 100000$. That's my point of view...So if you're ready to bet, then 2700$ or 3400$ a BTC is the same...
