Another point you could add is to advise people not to panic buy or sell. Even if you missed a boat on a coin, it is dangerous to chase a coin. There are many altcoins in the market and opportunities come often for you to buy a coin at a cheap price. Don't panic if you see your coin crash. Altcoins are volatile and if you hold for a few days/weeks, it will almost creep up to the price you bought at.
Yeah, it's very important to do the research and make your own judgement. Stay calm but don't try to fight against the trend or be too greedy.
