How many of you HODL and how many of you trade?

I'm pretty new to crypto (few days deep), not much invested so far but I'm up about 15% from my initial investment.

Two of my friends buy crypto, both somewhat successful so far. They both do a lot of research on the coins they buy (as you all should) so they can get a good idea of how the coin might perform in the future.

One of them buys and hodls until they can sell at a good profit (or loss). He claims to have made over 10x in some trades by simply hodling. He does do short trades, but very rarely. Although he has lost quite a bit hodling, since his overall portfolio is in the green he's convinced that if you hodl long enough you will come out on top. He says his portfolio is around 80k from a 20k investment.

The other friend buys and sells, typically within a few hours sometimes days after buying, for small profits (or loss). These small profits add up though.. he started off trading with only $1000 and his portfolio is now worth over 200k.. he claims he never added any funds and that's all from the initial 1k investment.

I've been hodling a few coins and trading others for small profits. How do you all approach crypto?
