Singapore makes regulations first before crypto or Bitcoin begins to be used as a means of payment for transactions for goods or services, they care about the friendliness of developing technology, so it is necessary to make clear regulations as a legal umbrella, both to maintain economic growth and early detect money laundering caused by transactions involving crypto.
I do not agree, that this country is a place to hide regulatory obstacles to legal umbrellas in other countries, because they also make special rules governing this issue, which distinguishes Singapore from other countries only in terms of "regulatory certainty" or guarantees for industry players and consumers. also guaranteed to know information about companies that can be trusted.
Singapore is also a country that has a huge income for every native and immigrant, allowing bitcoin to grow rapidly there, and it is possible to achieve status as a Bitcoin hub and become bigger like El Salvador.
Singapore is not going to announce bitcoin as the main currency like El-Salvador. What Singapore is planning is to create a legal framework for the crypto related businesses. Singapore is well know for their business friendliness so it was very much expected for them to create a framework for everyone's benefits. This will possibly allow its citizens to use bitcoin as a payment method but under no circumstances, bitcoin will be notified as the main currency. Singapore's administration is quite well educated not to take such suicidal decision especially when they have an example of El-Salvador.
But yes, with the help of the legal framework, Singapore is possibly trying to become the crypto business hub for the world. And with their determination and corruption free administration, they are highly likely to achieve that.
