Dear big shots, I am a businessman, new to the crypto world, completely inexperienced in trading cryptocurrencies. I just want to hold some coins for long-term investment, without worrying about short-term fluctuations. I plan to leave it for my descendants in 10 or 20 years. I wonder if anyone shares the same thoughts. I hope the big brothers can advise me on whether it's feasible to hold virtual currencies, which coins are relatively safe to hold, and any suggestions on what I need to pay attention to!
