for the moment for me the price of bitcoin does not really matter, because that is important to me is the number of bitcoin that I currently have and how to make it more and more. although bitcoin prices to be high at the moment but I do not have a bitcoin, I think it will be worth it, so I'd rather worrying that the current bitcoin I have than worrying about the price
It's good that you look to increase the number of coins that you have, but don't get stuck into that thought too much as it may work against you at some point.
Instead of investing your precious coins into a site or service, or altcoins and their scammy ICOs, better focus on developing some BTC/fiat trading skills as that is a much better option.
Trading BTC/fiat is how smart people increase the number of coins that they have. The repetitive nature of the price can work into your advantage real nice.
But you have to know what to do. That's why developing trading skills is essential for the short and long term.
