Around every four years, there is a halving event where the block reward is halved. This reward is the only way new bitcoins are generated and it's paid to miners.
Thus every 4 years, the rate new coins are created also reduces and it can lead to speculators pushing the price of bitcoin upwards because of the reduced supply of new coins.
If so, may I know what kind of gift sir is celebrated every 4 years and can all users get the gift?
But I see now that there are also many new coins, some are cheap some are expensive but have not been able to push the price of bitcoin to go up.
I see you have been joining the forum for a long time, but I don't know why you don't understand the term 4 year reward?
What the OP means here is a gift (halving day) which occurs every 4 years, and it is a form of cutting the amount of reward (reward) for miners to half of the previous amount, when we (miners) perform digital validity in each transaction then they will get a reward (bitcoin) according to a predetermined amount, so if you want to get the prize, of course you have to do bitcoin mining now.
Block reduction that occurs every 4 years will certainly trigger the availability of the total number of bitcoins, and this has an impact on demand which may be greater than supply so that it will eventually trigger an increase in bitcoin prices.
