So the halving mechanicly is not the trigger which would make that sick rise in the BTC price that we all expect. People and their greed will make the halving bubble puffed as many will buy BTC to make halving profit, so people holding BTC and not selling it, and many others trying to buy them will pump the price since the demand will be greater than supply.
After halving my guess it that the bubble will explode hardly. WHY?
First of all miners will get half reward then they do now before halving occures. If you watch the news you can see mining farms getting shut down because it's no longer profitable to mine BTC, it's profitable only in China and similar countries with low electricity price. Some people already predict there might be a lot of delays with BTC transactions after halving occures since there will be a low number of miners.
Second, people will just seek for another train to get fast profit and those trains will be Ethereum and Lisk for sure, especcialy after the halving bubble, Ether and Lisk prices will be low.
Third, BTC is popular in the whole world, it's the first crypto currencly and this is what will keep it alive but new technologies such as Ethereum and Lisk will just take a big chunk of BTC market as they keep rising fastly. Ethereum already has more nodes than BTC, it transactions are fast, there is no fear of mining stopping ever because of it's POS system, their potential is huge and it's still 99% unused since only few simple dapps are online.
well yes miners will get 50% less, but price rises now so i am also pretty sure that it will rise after halving too, so bitcoins miners will get same or even larger profit than before halving
and yes etherium was very, very popular month ago and many people bought it just to get profit from it, but it won't have very huge impact on bitcoin as people will still use bitcoins
