I agree, timing is very important and I think OP is at the right timing now since bitcoin has recovered a bit.

Aiming for that increase is realistic, bitcoin has already increase a thousand times that's why it reached it price now, so I don't think it will stop at the current price when the fundamentals are good. It will really take time and every investors has to be patient, the word HODL is popular when investing in bitcoin because everyone is require to hold.

Investing when the market at dip is good, it helps us get a cheaper value and will lessen the time of holding but BTC at 10K, I still believe it's a good entry price.
