The total amount of Bitcoin to ever exit equals 21million and and after this bitcoins have been mined there will be no generation of new coins into the system, and this will causes scarcity (limited supply) thereby increasing its price. According to the law of supply and demand in economics which state that as supply decrease, while demand remain unchanged the price increases. This theory can be used to predict that Bitcoin would be able to ascertain of height of price worth millions of dollar, having this knowledge I recommend that buyers should go into long term holding of Bitcoin as each halving comes with reduction of coin supply.
Total circulated coins from 2009-2023there are 19,452,931.25 total circulation of Bitcoin in the world, remaining 1,547,068.8 to be mined for the next 116 years to come, and after these coins have been mined there would be no more block rewards for miners who successfully guesses the block number, the only payment they'll get at that time would be the transaction fee for every transaction in the block which they validates, and these transaction fee can only profit the miner if the fee surpasses the expenses of the mining farm, and this can be possible when the acceptance of Bitcoin by nations, companies, businesses, etc increase to a reasonable amount whereas also increasing its transaction rate, though miners are now beginning to use renewable energy source for mining so as to increase profit but this will not guarantee their satisfaction.
BTC circulation till the end of the halvingThe current block reward for mining is 6.25 Bitcoin for an average of 10minutes which is regulated by the mining difficulty so that coins are not mined too fast or too slow, the mining difficulty increases if it takes less than a week to mine 2016 blocks while it decreases if it takes two weeks to mine 2016 blocks,
This difficulty will eventually frustrate some miners to quite especially when mining reward gets to 1satoshi per block, even it Ai are used in future mining to increase efficiency and speed they can not exceed the mining difficulty.
ConclusionNow is the time to go into mining and buying of Bitcoin as each halving reduces the block reward by 2 which causes scarcity that has the potential of increasing price.
