A great small business always starts out as an idea, but you have to transform that idea into action. You have find services or products you can offer and get paid in Bitcoin.

Here are few steps I could recommend you:

1) Do some research to identify a business idea. Look at the potential to succeed. Generally, a good idea = something solving a problem, fullfilling a need or offering something needed on the market

2) make a small plan to approach the reality. Your business plan will guide your business from the start-up phase till business growth

3) Plan your finances: for small business, don't seek to invest lot of money. Instead, make use of your Best skills - what can I do best? What are my best skills? These will require less financial investment than your "brain" - which is highly valuable

4) Start, analyze, review, make changes and grow up

Good luck with your business
