I have purchased a variety of currencies and gained dozens of times the profit. Now I will share my experience with you. First of all, I would like to introduce a selection method based on personal cognition, which is suitable for those who have a certain amount of experience.

1. Check the background history of the founders of the currency. First exclude domestic founders, then exclude founders without financial strength, then exclude those who have been involved in improper behavior, and finally exclude those who have harmed the interests of investors.

2. Determine whether the currency is imagining a bright future, that is, it is a copycat currency but openly claims to surpass Ethereum, Bitcoin, etc. In addition, those currencies with vague concepts and no practical applications but with high-sounding banners should also be excluded.

3. Pay attention to the currencies that are hotly discussed in the group, especially those that retail investors make profits on every day. In the cryptocurrency circle, you should always avoid following the same trend as retail investors.

4. Avoid buying currencies whose prices have been falling for three years and have not increased, that is, those currencies that fluctuate and fall frequently. These currencies have long been manipulated by market makers, and retail investors have fallen into a vicious cycle, which has lost the meaning of investment.

The second method is probability-based selection, which I have also tried.

1. Choose the currencies that have been listed on Binance or well-known exchanges such as Binance, EURUSD and Coinbase. These currencies have at least passed Binance's project review and paid the listing fee. They have certain strengths. Even if they are virtual assets, they are screened and strong currencies. You can try with a small amount of funds.

2. Pay attention to the coins with a price between 0.0000 and a market capitalization between tens of millions and 500 million.

3. Give priority to currencies founded by foreigners.

4. Pay attention to those currencies that have not been obviously hot or heavily promoted before.

5. Sort by market value on Binance and select several currencies to invest in. The purchase amount does not need to be too much, a few thousand or a few hundred yuan will do. In a bull market, the funds may grow to tens of thousands or even hundreds of thousands of yuan, which is normal.

The above two methods overlap with each other and all conditions must be met at the same time. If one condition is not met, the currency is excluded. I have purchased several currencies through this method and have successfully made a profit several times a year.
