there are only two ways of investing in my opinion and i am only mostly talking about bitcoin:
1) you day trade to make more money, or bitcoin whichever you choose and in that case you sell on top and whenever you speculate a drop such as the FUD about split and then buy back at the bottom and rinse and repeat the process every day
in this case the drops and rises matter
2) you go long. in which case you buy at current price, preferably in a dip and hodl. no matter what happens in short term. and you do it only if you believe in bitcoin in the long term.
in this case, price going down doesn't matter at all since you are always in profit.
Well seems like criteria of number 2 is suitable for me, i personally buy bitcoin as much as i can, collect and hold them for long term investment purpose, cause i truly believe that bitcoin's price would be sky rocket in many years later that's why i am not worried whether the price down or up even though just a little. Trading bitcoin at this point would not make you rich except if you have a lot of money or bitcoins for doing so. So far long term investment is a good option for me, i have lost the chance when the price was 200 dollars i didn't buy much bitcoins at that time, now i would not lose that chance again.
Well with the Bitcoin's price right now which is 960$ per Bitcoin for is still expensive for it to be holding. I won't risk earning only 200 $ with this kind of technique. Of course there are many ways to earn money but Bitcoin being unpredictable it is hard for us to buy right now. Maybe on the price of 700$ way back January, I would have bought Bitcoins but right now it is too risky to buy Bitcoin.
