Some friendly advice

Hello everyone,

Last year i was thinking what crypto currency to invest in and last year i read often it was avalanche. I now regret not taking the shot. Are there any highly promising currencies for 2024 or is avalanche still worth it?

I've looked through some other ones but noticed just a few have had a steep curve during the past months. Uniswap or solana are some I've read about?

Is it wise to divide investments to about 20 different currencies or do some research and choose 3-5 promising ones

Apologies if i don't use any technical terms I'm an absolute noobie who didn't made the decision and missed out on like 2 years salary lol.

Any advice is welcome

Cheers
