I'm new to cryptocurrency trading and I wonder if you can share what you follow for sound investment advice.

Do you know of a source whose advices were most often good in the past ?

I do not know if they're good but the cryptocurrency channels I started to follow on youtube are:

Young and Investing
I love Crypto
CryptoFuture
Crypto Gurus
Crypto Coins
Crypto Decoded
DataDash

PS: My money is mostly on Substratum now and some is on RaiBlocks. Substratum is expected to start testing beta version of their software in the middle of this month and RaiBlocks is going to be listed on Binance due to coming on top of the community poll and Binance is a much bigger market than the total of the market RaiBlocks was on until now. I made mistakes, I'm trying to learn better.
