The thing here is that, you are never too late. You can always buy Bitcoin and hold it if you want to get the profit that you want.
1st BuyNhold (Will take you years before you even get rich and thats if you put millions into BTC which I dont have) the low low prices are over, which now you require massive capital
You don't need to buy the whole Bitcoin, you can buy in fractions which is convenient if you currently don't have to capital to invest in a whole Bitcoin.
If you are not confident trading Bitcoin to get more, then you should present your skills to the community
here. You can find different services there and you might have the skills that the people would want.
If you don't want to do that, then just convert a portion of your money you get from jobs outside crypto.
You are not late man. There are still profits to be made.
