Bitcoin will rise and never stop, no one can stop bitcoin, it will slightly goes down sometimes in a very short while but it will continue to rise and become popular till the time that it is already a "fiat" currency online. better to hold it and save for the future.
Actually the down movements will make the bullish movement even stronger. Here is the argument: Bitcoin gets more diversified by ownership. Therefore, one owner has less coins and his selling target is therefore higher.
In the future try to get 0.1 btc.... We will be amazed on people who are so wealthy that they own 0.0001 btc so every bit counts that you are able to rake from the poor sellers these days of cheap btc.
Exactly it will be much tougher in future to earn bitcoins as the value would be too high so at a moment don't miss a single opportunity to collect as much coins as possible.
