" Bitcoin is still the Investment Exposure of Institutional Investors. " Thats the topic of this thread while you did not say anything about Institutional Investors in your post.
Leverage tokens are nothing new. They are available on many trading platworms such as binance - far more legit/reputable/reliable/safe than MEXC. How they works is explained everywhere. For example here:
https://academy.binance.com/en/articles/a-beginners-guide-to-binance-leveraged-tokens-blvtWhat is worth to say is that those tokens are ment for intraday trading. Not for long term investments.
It is explained in the link you already provided:
https://www.binance.com/en/blog/421499824684901079/Why-you-shouldnt-hold-leveraged-tokens-longterm-"Leveraged tokens are built to multiply the underlying asset's daily return-the main component to remember here is DAILY. The leverage factor of a token will be reset every day. As a result, the performance of a token and its underlying asset can differ over the long term."
If BTC will dump 30% in one day you will lose 90% (100$ left from 1000$ investment). Next day BTC will do +50% (back where it was), you portfolio will do +150% from 100$ (250$). BTC recovered the dump but you are still 75% under water. In long run it sum up to be the worse long term product.
