1.How did I lose my bitcoin?
I learned about the ETHBull and ETHBear Token which is the 3x leverage token of the FTX exchange. The price of ether was then below $ 100
At that time the price of ETHBear was $ 30 when I invested.Then the price of the Ethereum was around $ 120. At the same time, I panic and I made all my investments on ETHBear in the face of huge profit.
2.Big mistake of my life

this investment was done at the behest of a youtuber which proved to be a big mistake in my life.Now I have thought that do not invest at the behest of others.
When I lost my entire BTC, I felt very bad, please do not do it.
Thanks for all
