Bitcoin (BTC) , the most famous and valuable cryptocurrency in the world, is about to undergo another halving – an event that halves the reward for mining new blocks. Scheduled for April 18, the event usually has a significant impact on the movement of Bitcoin.

This year, however, there is an additional factor that could further influence the market: the approval of Bitcoin ETFs in the United States. The listing of ETFs on the American stock exchange had a positive effect on the crypto market in March, causing Bitcoin to reach its all-time high above US$72,000 .

However, after a highly positive boom, the performance of the market's main crypto has followed a downward trend in April.

According to experts, this movement can be attributed – in part – to the approach of the halving. And to understand its possible impacts on the price of BTC and the entire crypto market, it is important to revisit past halvings, as well as monitor what the market's main expectations are for this month's event.
