best in what way? if you're talking about risky but profitable then holding cryptocurrencies that have strong support. if you want something with minimal risk but far less return you're better off going with mutual funds.
If one want to take advantage of investments, then try to diversify your funds and invest in all different products then over the time your profits will go higher. We shouldn't keep all our funds in any single product or company, try to put them in as many as good products. I have invested in gold, real estate, shares, mutual funds and bitcoins.
It was very good for you, but I'm concentrating on things that are different, I have principles if it wants to master in total it should focus on a few parts. I chose to focus on two things: investment in property and cryptocurrency. I invested a large part of capital only in two parts, focus will yield greater profits, in contrast to investments in many businesses but use less capital.
If you are a person who likes passive income, you are right, but if you are and expert in time that's always determined-focus on large amounts of investment in 1-2 places is the best thing.
