Do I understand correctly? If BTC is low cost, we can buy it also by lower price? good news
Yes, this is correct indeed!
However, for the current holders of tokens seeing a rise in the market price is usually a good thing because their token value increases. The same effect can be extrapolated to the entire crypto market because a price surge means growth in the market. This encourages new investors, while the existing investors gain more value for their investments. It also drives demand, which is directly proportional to the price.
Yep indeed that's right. I am also one of those who's hoarding coins right now because I am looking forward for the bull run and halving that's why I am keeping my coins. When I heard the news about halving this year I am really happy because I have a lot of coins to sell for a better price and I can shout this line "it's payback time!" if that will really happen.
