In my opinion If you want to get Ethereum easily and there are no obstacles and any difficulties, you can exchange services or items that you have today to get Ethererum like exchanging Bitcoin and with Ethereum. But there are other ways too. Besides buying in exchange, you can mine to get ethereum. But this method is very difficult in my opinion and there must be a high cost to buy special tools for mining. And mining is usually done with patience and usually, mining is carried out by large companies that have been able to fund their equipment.
