One of the main reasons why i do buy bitcoins is because the price increases almost everyday

I guess not every day bitcoin will rise,bitcoin prices can go up and down,it depends on a person's buying and selling bitcoin.
so bitcoin will remain expensive,I believe bitcoin will penetrate the rate of $2000 to 1 bitcoin
I still did not dare to buy bitcoin, but this is mainly due to two reasons, this is that I have bitcoin almost the only income, and also that I'm afraid of losing my money.
