This is what I experienced last year but I want you to know that pattern of crypto altcoin do change, because it happen last crypto bullrun doesn't mean that it is going to happen again because I learn that investors taste changes, they always go something new they can explore to gain the attention of everyone so they can make cool money from it.

Last altcoin bull run started as a result of Decentralized finance, protocols that were controlled by smart contracts instead of the normal traditional finance that we have and many existing projects all teleported their objectives towards Defi as it was the new thing in town and more demanding but later what kills this trend is that the number of hacks were much and a lot of teams were scamming investors, the trend wasn't palatable as it started and it die off but some projects are still available and improving on Defi.

We also had NFTs that time, non fungible tokens but also demands died off and now here we are with another season and we haven't see any trend yet. It could be that people are more careful now after what they learn from last season or perhaps they don't have what is sweet enough to invest in yet. So, just buy and hold some good altcoins.
