#比特币ETF Bitcoin has returned to $90,000. Lately, I've been seeing all kinds of analyses flying around, and I suddenly thought of a question—why is everyone discussing "technically driven" factors, but I feel completely clueless about what these key levels and support levels mean? 😅

After reading the opinions of several researchers, it seems the core idea is: the $90,000 level was previously a "resistance," but now it has turned into "support," and then the bears started covering, causing the price to go up. But honestly, this is still a bit fuzzy for a newbie like me. What's more interesting is that someone mentioned that ETF capital outflows exceeded $1 billion in December. Could this also affect the market trend?

Recently, I've been learning about what a Bitcoin ETF actually is. I feel this might be a good entry point into this circle—compared to directly trading on exchanges, using an ETF seems a bit "safer"? Could any experienced folks briefly explain whether Bitcoin ETF volatility also tends to follow the spot price? I especially want to understand the actual impact of institutional inflows and outflows on the price 🤔
