Not everyone can do what you do, although I really believe that some people in this space have income only from crypto, but it can be done by people who understand crypto.
For some other people they don't do the same thing, especially beginners. if they don't have income then they won't be able to invest. There is indeed income from airdrops, bounties or signature campaigns, but for those who don't understand it definitely takes time.
Good job guys when you use income from crypto for business, that is a very good thing.
Some people are just getting salaries from crypto but for it they utilize different methods and do not relying on just trading and investment as trading posses risk while investment requires prolong timing for offering profit.
Relying totally on crypto investment is not a suitable option because you will get profit after a long time so what will you do during such long timing if you don't have another source of income.
One should avoid complete dependence on crypto investment and if still someone wants to invest without using money from other jobs then utilize another opportunities in crypto to earn and then invest so you can handle all possible responsibilities as well as invest with good amount.
It is always good to find a way to do things better, personally I have always been someone who is very enthusiastic about crypto because it is a way to do things, if you have an income from work or something like that, it is always good Allocating some part of that money to investment, but only to investment, to trading is a little difficult to advise because I have always said that the best thing is to do trading with knowledge, with reading books, guides, technical analysis and many more. Other things, that's what I recommend when trading.
Cryptocurrencies will always represent money, therefore it is always good to diversify money there, of course the only thing I recommend buying is Bitcoin, Bitcoin for me is the King currency, without Bitcoin altcoins would not exist, so these are the types of things what we should know.
