You mentioned important warning for investment before a new handsome or decent projects. I think one one brave to take this big risks at the moment, A lot of scam projects warned and examples for investors. One way investment is huge risky in cryptocurrencies because it's a volatile market.
Investing is not that easy because you are risking your own money digitally since crypto is a digital currency. This is a good warning for everyone who is risking their money in some projects since not all projects are good because there are projects that are intending to scam people. In terms of portfolio, you should have a solid one so it is easy for you to make things clear and going out with your plan.
I also say that term of not keeping all eggs into one basket but in bitcoin, this is the opposite way. If you want to minimize your losses but to maximize profit, putting to bitcoin-only can be your choice. I have invested in other altcoins because it's my choice to diversify.
Bitcoin is a gem and if you have invested only into it, you have the best gem of them all. But as time passes by, you want to explore into altcoins and that's the start of knowing others of it through the researching.
yes, because investing in bitcoin could take a long time, unless the market conditions are good, it will easily increase.
investing in altcoin has different variants, because there are so many of them, at first it may be difficult to determine which currencies are worth trading.
The market is volatile in terms of the price of every cryptocurrency. So if you are holding a lot of tokens you should have plans to do so that you cannot lose your money. Diversification is one of a reason if you really want to hold one coin and give your full time on that and wait for the right time that the market will recover and to sell it on a right and perfect time. And as an investor, you should have patience because income in this kind of investment is not getting with just a blink of an eye.
