Hopefully we only have another 9-12 months before the bull run starts and I am just wondering those who have been in crypto for a while what the last bull run was like and if anyone has any advice on how to prepare?
You don't really need to know about anyone's experiences, because all the price history is written down on exchanges or services like coinmarketcap. The chart is all you need to know.
As you can see, in the past bull markets have started shortly after the halvenings. The next halvening is in 2024. So this whole year is not likely to be bullish, which is not a bad thing, it means that it could be an opportunity to accumulate more.
