if you want to invest in bitcoin, don't look at the value just invest, don't be fooled by the market swigs, there are only two things to do with bitcoin now that is buying and holding
keep buying no matter what the price it, and hold the rest, if you want to make more bitcoin from the one that you are hold, invest them in some other things like altcoin that have a great potential or mining
actually i never bought a single bitcoin, i like to generate them via mining, it's more anonymous for me, and more profitable, even if it's slower
This is the problem with a lot of people, they only see the current price of bitcoin and they see the high price and think they cannot invest in bitcoin anymore but the truth is as we have seen in the last months is bitcoin is going to keep growing and those which invest right now are going to enjoy the benefits of their investment in the future, while those which dont are going to regret it for the rest of their lives.
