I will go even further than this, teaching general principles about investing is acceptable, but the moment you give a specific advice about which coin is a good investment you are taking a significant risk, as even if the advice to invest in bitcoin is a good one, there are many people that have lost a lot of money with it anyway, and if you were the one giving the advice, you can be sure you are going to be blamed for that loss, and if the amount lost was high, there is even a chance you could be sued.
It is better to stay away from these things, not to give any advice about investing to others.
But we see now, many influencers just say that this coin is good, that coin is good and has potential, but there is no responsibility for those words.
We as followers or spectators must also be smarter, do not follow the words or investment advice of others if we do not fully understand investment.
It is better for me to provide knowledge about technical or fundamental analysis than to have to say to buy a certain coin,
because there will be no risk in the knowledge provided.
Everyone has their own investment choices and strategies, choosing coins is your own responsibility,
don't blame others if there is a loss, and also don't be too enslaved to someone when making a profit.
