You don't need to choose, you can do both to get more profits. opening a business while investing in crypto is not difficult.
It's not difficult you say? Invest in crypto and manage them are difficult task to do, it's not a game that you can play it whatever you want. But if you don't serious with this, you can lose lots of money.
I would rather choose to invest in cryptocurrency than opening real business because in our industry there are lot of competitors so that if you product is not popular you will no income and then it will lead to bankcrupt unlike in investing cryptocurrency all need to do is to wait.
Cuz you just sell mainstream stuff. Just sell a new brand and promote them.
