Most people will just advise you to buy what they are already hodling. This is really a big issue in the crypto investment space - trust. Do your own research of each potential coinand make your own decisions. I think we will see more index type investments become available in the crypto market this year which should allow you to spread the risk across a range of coins.
I don't think it is a trust issue...true that people recommend what they hold because they believe in it to begin with (otherwise why purchase/invest on it?).
Truth is, we all see different things on each coin/token. Many will get it right but most will be mistaken. Well meaning folks are eager to help and guide...not knowing/realizing they themselves are also lost.
In the end, DYOR is the best answer so you will not have anyone else to blame but yourself it it fails.
