Many people buy btc on the hype and then sell when everything is going down. Please dont do that crypto can make you rich but you need a strategy. Here is some of my favourite tips.
Everything is public on the blockchain , so find wallets of holders with a lot of bitcoin and study their behavior
2.Look at google trends sell on the hype buy when the hype is low!!
Have patience don't be emotional
4.Study charts
Don't listen to most youtubers talking about get rich schemes , no one knows actually
Do dollar cost averaging , im buying every week and only on days with red numbers
use a good wallet like trezor or ledger and keep your keys safe !!!!!!!
ALSO i want to give you a good tip for a new site called https://coingossip.club this site lookes at the discussions and posts about certain coins ,
