Distrust of cryptocurrency arises as a result of owning a small amount of information about this innovation. If you inform a person and show him positive results on someone else's example, there will be no fear to invest.
The biggest difference is that bitcoin is the first and original crypto, everything else is just altcoins, including Ethereum. I believe that each coin comes with its own unique use and benefit.
I like bitcoin and Ethereum. But the investment is very different and you need to choose the right one for yourself. I think by the end of this year the Ethereum may reach 2000 dollars
To invest you need to be confident in the project. I recommend to carefully study the information about the project, learn about its uniqueness, read reviews from other users.
For me, crypto is an additional income. I like it for simplicity. I believe that in the future you can make a lot of money on this. I wish you all good luck!
