Hi Catalin,

So good to have you here with us at Guitar Tricks!
Congratulations on all of your progress so far!

You ask a very good question. 

As musical styles, the Blues and Country music are rooted in an acoustic tradition, pre-dating the existence of electric guitars!
Both styles sound great when played on the acoustic guitar.

However, as time has gone on and electric guitars came on the scene, it has resulted in some Blues and Country styles and techniques that are best suited to electric guitar. 

I would recommend you get started with the Blues, and/or Country lessons, on your acoustic guitar. 

And if you find yourself really wanting to make some of the sounds that are best played on an electric guitar, you might try to get yourself an electric guitar! 

Most of all, have fun! 
- Lisa
