The stock market returns about 10% a year. This doesn't happen every year some years might be below (or even a negative return) but typically over longer spans of time (like 5 or 10 years) you can expect a 10% return. Anything else is probably a scam, even mutual funds that advertise 20% returns only do this for a few years and over the long run fail.
This isn't to say that you can't do better than average but the average is about 10%.
Stock market returns average about 10%
A sense of reason might be the first casualty of a bull market.
Investors get comfortable when stocks rise consistently. In a roaring
market, stocks seem to go only up, up, up, and 30% returns appear
perfectly normal. Everything you buy turns to gold — but then comes
the crash.
Over time, stocks, as measured by the Standard & Poor’s 500 index,
return about 10% annually. The index comprises America’s 500 largest
publicly traded companies and is considered the benchmark measure for
annual returns. When investors say “the market,” they mean the S&P
500.

As far as anything associated with bit coin, you can make nice returns, but it is extremely volatile and the price is based mainly on belief (whereas a company has assets that are worth something if things go south ), and as of now the hype is dying down and so is the price. I would stay away from anything related to a high risk investment. Before investing in any opportunity, you need to know how they are going to make money. So look at other players in the market and their returns if the information is available. 5% a month or more seems way to high. The other big red flag is the return goes up with the amount of investment, which incentivizes you to give up your money, and is unusual for most investments.
Do yourself a favor, find a nice medium risk mutual fund to invest your money in and get your ~10% a year.
