Hi! It is too soon to say the future. This thing is just getting started, it is like a gold rush.
There are people getting scammed and tricked, but also there are talented artists, in the long run the gold still has value, it is just not clear for everybody.
I suggest you to keep doing what you like (3d modeling) and through time get better at it, as well as trying your own NFT projects. Remeber that giving value to others is always the key to succes and to make money.
Personally I had a good experience working for others NFT projects, but from start I am very blunt on the price of my work, as well as to create a network to do more projects in the future.
