All industries should still be able to make money but when it comes to which industries can make money fast then it really depends on the reach of capital that we have.
Take one example if someone is involved in the property industry then with a small amount of capital availability to make money in that sector is very limited.
The best opportunity might be involved in crypto investment and especially bitcoin because the growth of this industry is increasingly advanced for now.

If you want to be successful then look for something that can produce and even though the availability of capital is small but can be developed slowly and bitcoin provides that opportunity.
