"Dont put all your resources in just one possibility"
Im trying to say that dont risk at investments because most of investments were scam and its just a waste of time and your money
so i suggest you to save your money 
and not to invest it as well.
I dont agree with you completey.I agree on the fact that many investements are scam these days and we should not invest with proper knowledge.But investing is important if you wanna grow your money.But yes investly only if you got some good oportunity to invest.Im trying to say that dont risk at investments because most of investments were scam and its just a waste of time and your money
so i suggest you to save your money and not to invest it as well.In the early days of the bitcoin, 99% of bitcoin related investment were scams, the proportion has reduced now.
that has never been true because those 99% that you have in mind were not investments!
it is too simple sometimes that it baffles me how people even call some of these "investment". when you see a nice site with nice pictures that is saying we will give you X% profit without any real business to back it up then it is a clear example of a scam.
are you calling these investment?
The word "investment" itself means to give away your money into a business (no matter what or how it is) in order to get some commission or profits out of it in a particular time, so now if the business scams you and run away though you knew it before if you had sense, that is still called an investment.
