The halving is a process that happens under proof of work blockchains, that is, mining with hardware, from time to time, or rather every certain blocks of transactions, the reward that miners receive for validating these blocks is reduced by half. For example, in Bitcoin it is every 4 years, or 210,000 blocks, before the first halving the miners received 50 BTC per block, in the first halving it was reduced to 25, in the second 12.5, in the third 6.25, which is the amount current and now in April it will be reduced again and they will receive 3,125 BTC each block.
Quite the opposite, if you look at the chart, some time after the halving the price rises a lot, and I explain why, miners start to receive fewer bitcoins, so fewer bitcoins flow to the market, if the demand remains the same or increases, there will be a shock in the supply since there are fewer bitcoins and the market perceives it as more scarce, which causes its price to go up.
Yes, of course, although I think that with the gains that the market has left lately, most investors in this halving cycle should already be making money in the market or very close to it.
