The significant rising in bitcoin price maybe because the bitcoin halving period is gonna happening. Indeed it is the best time to buy some bitcoin.
But if bitcoin price rising after halving, usually the other altcoins price will rising too because btc. If you think it is a good time to buy, then just buy it what you can afford to lose.
Indeed, Bitcoin Halving will always have a positive impact on price Bitcoin and Altcoin, so it's better to buy Crypto before Halving happens, because if you buy after Halving then you will get an expensive price. That's what I experienced with all the Halving in the previous year.
in fact, nowadays people save bitcoin more than altcoin. however, some other facts are, we know that the increase in the price of bitcoin can be more dominant than the price of an altcoin. so, make sure you choose altcoin which can really take advantage of the current bitcoin. however, I also stocked some ethereum for that.
