#FIO I discovered such a thing today and am debating whether to buy it. To be honest, I don’t understand what it is at all, but in terms of trend and transaction volume, it is almost not affected by external forces and can basically synchronize with the big pie. The total transaction volume is a pitiful one million. This liquidity confuses me. If someone suddenly pulls it one day, it will definitely be easy. I was once violently pulled, and then fell all the way. If there is a bull market and you choose copycats, I think there is still a chance for this thing.
