I very much understand as our both situations are quite similar.
Over the last years I paid a fortune to 'advisors', but most︀ of them still gave wrong advice and they're not even liable for it.
Day Trading︁ is something they dont seem to understand and most tax laws were not made for︂ it.
Spain with Beckham Law - I didnt look deeply into it myself as some︃ friends wanted to move there and they ran into issues with the Spanish tax office︄ (which seems to be quite nasty).
Main issue, as I understood, was that if you're︅ the one 'performing' the trading, you may run into tax issues.
I'd love to that︆ Spain Beckham law would work, but to be honest I think there are a lot︇ of potential traps.
For Malta, ask your advisor if you can get a tax ruling︈ from the Maltese CFR.
Tax rulings are usually done by declaring the tax office what︉ you are planning to do and then get their opinion about the potential taxation.
The problem with EU countries what I see is that eventually they will apply exit taxes︊ on unrealized profits like Scandi countries, Germany or Austria in a way already apply.
But, the main thing, specially when raising a family, is to optimize over many variables like︋ quality of life (real life vs expat bubble in gated community), security, education options, how︌ you like to live there and many other factors.
I'm since nearly a decade hopping︍ between different jurisdictions, but I think its good one day to accept to pay reasonable︎ taxes if you like to live there.
The times of legally paying 0% sooner or️ later will end if you want to live in a 1st/2nd world country.
3rd world countries will give you more time, but to be honest it's personally nothing for me to live a longer time in the ones I visited...
