It's still tax evasion and likely you might even get caught depends on how much numbers are we talking about.
Why not try to easy way, look for the buyers in your country and willing you to buy directly after you being agreed to a rate, like how we see the trades in the classic gansta movies.

There will be no payment trail at all but you may need to prove the source of funds whn you spend money from it and that's when lawyers and accountant will come in handy but you said job so I doubt the numbers are that big, I might be wrong so don't stress yourselves.
Why not just keep holding?
I started with 20k euros 1 year ago and now the account is at 50k euros. I believe I can hit 80k or more after the summer here.
And I aim to increase this portfolio every year.
It is not a lifechanging amount of money yet, but with good management it can certainly become just that.
So face to face is the realistic solution, you may try the currency exchange section if any forum members interested in the deal but you also have to be careful with face to face because there's a lot of pitfalls on it too, but for safety concern meet the buyer in the public place and split the deals into a few to reduce any risks.
About the growing part, yes it's definitely possible and with a little play around once in a while like buy the dip and sell when market hits peak then the compounding will kick in.
