halving expectation is there, and btc price may keep in a rational range for a time before it explodes.
so maybe it is good time to buy alts to get more btc now?
If you want to earn more btc better to trade bitcoin not Altcoins , the price of Altcoin is much more volatile compare to btc, normal thing that always happen if bitcoin price increase altcoin price decrease and you will lose in bitcoin value its always happen every time bitcoin move higher.
Buying altcoin is not a way to increase your bitcoin holdings.
it can happen but the increase in the price of bitcoin is not always followed by all the decreases in altcoin, although some altcoins decrease when bitcoin increases, in my opinion for example we want to buy altcoin at this time to add Bitcoin and it can happen, because for me in buying altcoin it doesn't make bitcoin as a benchmark of the decrease in altcoin that we buy will decrease because of the price increase on bitcoin.
