Investment is not what we can do without having consideration for the plan we have toward it, because this one of the reasons why some have failed in their bitcoin investment, aside from knowing on what to do, we also have to take time to know how to go about making an investment in a profitable manner, starting from the fund to use and the necessary strategies we must employ to have a better experience in it.
Since we are in a bitcoin forum, let's focus on crypto investments in general. Well, i agree with you that any kind of investment requires a minimum of knowledge. On this basis, i see demo trading accounts are one of the few best solutions to learn about crypto investments and cryptocurrencies in general for newbies. No one could teach you how to invest in virtual assets better than practical tasks, and since it's an important mission, it's better not to practice with real money until full general understanding of how things work in this field.
