I live work and bank in the US but I am a European citizen. I have two options:
A) Buy cryptocurrencies on US exchange platforms such as Kraken with a CC or bank transfer
B) Buy crypto on a Luxembourg exchange such as Etoro with a US credit card
Which would make the most sense in terms of tax/regulation/easiness to use?
Many thanks
Buying crypto on Etoro is not the same as in fact buying crypto. You do not have the option to transfer those said coins to your wallet if you at some point wish to.
If you buy crypto on Etoro you are buying at CFD which tracks the underlaying price movements of the coin.
