I think this is a good idea considering that bitcoin can bring a million benefits and convenience to its users. Before the bitcoin price rises we should buy more coins and we sell when the price of bitcoin rises, so we will get a big profit. Keep waiting patiently to get a higher bitcoin price.
For me fluctuation is good as we get more chances to buy at low price and to sell high price, and investing now in bitcoin will give you best opportunities to have good life, as price now is cheap but 2019 is confirmed by experts as bull run year so better to invest and if you have try to hold and wait till end of 2019 I am hopeful about 2019 price increase.
Every single opportunities need not to be wasted, having in bearish season will be the huge chances for us. I know it is a little bit sacrifice for us to wait a long days before bull run start but this is the way to build our mindset for good and we can be surprised for its return.
