It can be bought easily and is very convenient if the person who wants to buy it comes from a country where crypto is legal and those exchanges are allowed in that country, which will make it easier for the person to pass verification and use their payment method without any trouble.
The first easy step starts with easy verification. But if you are from a place where crypto is not easy to buy, then you will need a little bit of research before you can buy bitcoin and hold it. It's when you know your way around restrictions that everything can be considered to be simple and easy.
Yes exactly buying Bitcoin is very easy if you live in country where it is legal. The process is simple with easy identity checks and no trouble using your usual ways to pay.
However if you are in place with strict rules against crypto it becomes much harder. You will need to do careful research to find way to get around these rules. Key to buying and holding Bitcoin successfully is knowing and following local regulations no matter how difficult they are. And in these days I do not think it is too much difficult because everything is online. Main problem is converting Bitcoin to local money in those countries where Bitcoin is not legal. Other wise Bitcoin buying in not difficult these days.
