It is true that Switzerland it is very popular among projects related to cryptocurrencies, but in my opinion the world capital of crypto is Malta.
I know Malta want to be a base for crypto in the past but what advantage can they offer. Would cost of power be quite relevant still, there is surely some cost perhaps labour that is most vital to crypto.
Switzerland could be good just because it has a fairly open attitude to all business. Classing crypto as securities means it would not normally be handled by ordinary public where as money usually is, but this also depends how much difficulty they put into anyone holding securities as a free member of the public. I assume there is no great difficulties to do so and its purely a disclaimer type difference
Malta for sure is not good place to open crypto mine, so for sure it is not about costs of electricity.
Malta is a good place for all kinds of commercial activities based on cryptocurrencies - mainly exchanges (for example Binance). It is a comfortable place when it comes to legal regulations and taxes. The government is very friendly to cryptocurrencies - this is the main advantage.
