So in let's say 10 years it would still be possible to mining ?
Yes. I forgot the exact year, but I think mining stops like 2120 or something? So you have a long time
If you are thinking of mining check out the forum section on that. But basically your main limiting factor is the costs of your electricity. In my area it is 20 cents kwh base plus scaled with use, so even if I got all the hardware for free I would still lose money. There is a lot more to it that that, but if you have high costs like me then you might want to check out Bitmain's services instead. You can buy one of their machines and they will host it for you, you pay a maintenance fee but you can still make money with it. Some people will tell you not to bother mining because you can't do it anymore. This is obviously not true, but you should be careful to look at the numbers before spending the money on it.
