Honestly I also don't really know why BNB went up so significantly lol. But I have always believed in BNB and have regularly invested in this token because BNB is backed by the exchange and its creators who seem to really care about crypto developments, so it seems very good to invest in this token.
For me BNB is another option besides Bitcoin because BNB can also still fall when Bitcoin is not moving upwards, although the support from the creators and the BNB exchange itself is always much greater. But I always put it on the second choice when I want to buy for investment and also trading.
BNB is good, but to me Bitcoin has always been much better.
