Just to add here a bit, only do business if you are confident in it. You can't just get a source of income from any business, instead you can loose a lot of money if you are not dedicated and give time.
It's obviously not a good idea to start a business first without a proper business plan and evaluation of each and every situation and outcome that can be faced after starting the business, and it should only be executed if everything seems possible and is set to work just as planned, otherwise, it will only go in vein and the money will be lost.
About Bitcoin trading, I partly feel the same way because I find it relieving and it probably will also allow you to have more free time if you are a full-time trader and are earning a living through it. But, I think it's only possible if you have a pretty big capital, to begin with.
