The daily volume Bitcoin ETF didn't went higher than March, although it's rise compared to previous months. This mean a lot people buy Bitcoin in centralized exchange, not the ETF version.
The correction has not occurred until today because Bitcoin is still flying until it has passed the price of $80K and even almost touched the price of $82K recently. And I think this is the moment where Bitcoin continues to show a fairly good and positive trend in the eyes of everyone so that investors who still hold Bitcoin will feel a very extraordinary impact and this can also give birth to more new investors in Bitcoin. In addition, traders are also quite active at this time because they see market conditions that continue to improve until now.
In bullish market, being an investor is better than a trader because if the price keep rising, the trader will able to maximize the profit, instead investor will accumulate the profit until they sell it at the peak. During this time, most people looks smarter because they're correct predicting Bitcoin market will go up, while actually without you predict, the market will go up as it's own.
