The unit price of bitcoin has gone from US $0.00076 to US $60000 now. In 12 years, it has gone up tremendously. No matter when you enter, if you don't grasp it, you will not earn or earn less; if you don't leave, you will still have a chance.

The price of bitcoin goes up and down from time to time. Some people enter the market at 3K and leave the market at 5K. They miss the opportunity to make more profits at 40K and 50K, and then wait for the opportunity to re-enter at a high level. Some friends can see that the market is calm and lonely. From 3K to 6W now, the number of bitcoin is increasing, and they are still optimistic.

Short term investment, short-term ups and downs, daily panic, watching the curve constantly fluctuating, a trading operation down a calculation of the income is still very little; and some people can not afford to worry, hold longer time, can feel the growth of wealth index.

I know a girl of 90 years. In 2018, more than 3000 bitcoins entered the market and bought a BTC. Later, she bought a BTC when it fell. Now she has accumulated 20 BTCs, and her wealth has soared.

Bitcoin price curve continues to change, no one can accurately predict the next second, no one can enter at the optimal price.

Making profit / loss plan can stop profit and loss, not be greedy and not be afraid. Only in this way can we survive in the currency circle and realize wealth growth.

The currency circle is a market with huge changes. New technology and new currency are constantly emerging. We should choose currency rationally, do not understand, do not participate, and plan carefully. After all, it's hard for people to make money beyond their cognitive range.
