Everyone should do due diligence on any token before buying as no one will be responsible for any loss. I also think that investment in FUN token is good as this coin has good fundamentals but I would never recommend putting everything in one coin. Diversify your portfolio and invest only a certain portion of the portfolio in FUN tokens. The current prices are too low and if this coin performs well in the alt season, then for sure we can get good returns on investment.
Doing due diligent research is necessary for everyone who want to spend money for investing or trading but it is not enough. They must understand two more things. First, the market is a zero-sum game so if you win, someone else loses money. If you lose your money, someone else win. It's not a market for everyone to win even Bitcoin has very good growth since 2009, there are people who lost money by investing and trading in Bitcoin. If they entered and exited like buy high, sell low, they are losers and they can not blame it on Bitcoin or call Bitcoin is scam. Bitcoin is not a Santa Claus to bring gifts, profit to everyone.
Second, they must not invest more than what they afford to lose with investing or even with trading.
