If you are confident enough in your ability to make money, then instead of crowdfunding, you can also use borrowed money to fund yourself. Crypto investing or trading is always risky, there is no guarantee that you will always make a profit even though you may have been very successful in the past.
There have been many cases of raising capital for trading and investment, promising a fixed monthly interest rate, most declared bankruptcy, losses after a while, the trustees almost can not get the money back. As matters related to Cryptocurrencies are mostly not government sponsored, we are solely responsible for our conduct.
Personally, I would not hand my money over to anyone in this market, even a reputable professional.
I am of the same opinion, you should not trust your money to anyone, no matter what they promise you. If someone claims that he knows how to make money, but at the same time he himself is looking for someone to borrow money from, then this should raise questions, why does he not have money? If there is a desire to make money on trading, then you need to learn this, if you can’t do it, then just buy bitcoin and wait, everything ingenious is simple.
It is true that there are always people who pretend to be nice and want to help manage the money we have, but these people are scammers.
If there is someone we don't know, then that person sends a message through this forum, email or our social media account, we should ignore
that person. Especially if he claims to be a professional trader, it's even more suspicious, because it's impossible for a professional trader to spend
time helping people he doesn't know. In the crypto world, there are many frauds, so be careful if someone offers any help, especially offering
something which is to be good to be true, that's a clear indication of fraud. If we want to make big profits in the crypto world, learn slowly from
trusted sources, because no one can get success instantly. As you said the easiest thing we can do to make a profit, just buy Bitcoin and hold it
for long term.
