What is Solana?

Hello to the crypto experts my name is Levi I am 15 years old and have been investing since September 2023. Since I would say that I am quite advanced for my age, I would like to broaden my horizons in the field of crypto! Since I already have a plan of $BTC (+0.1%) I now wanted to try my hand at $SOL (-0.37%) to try it. I would be very happy if a few people with knowledge, an opinion about Solana could be found in the comments and explain it to me. Ps: of course I've already googled and had a rough look at the project, but maybe more opinions will help! Yours sincerely, Das Bürschchen
