People will always be people. Filled with their negativity and pessimism mostly. But one shouldn't really do anything for their sake. If you're investing in Bitcoin, the opinion of your friends shouldn't really matter. Especially if you've done your research properly and you're sure it's the right financial investment option for you. Very many people don't even have sufficient information on Bitcoin. So, in this case, they are certainly bound to have the wrong opinion. You might opt to educate the reasonable ones. Maybe someday they'll also change their minds and join the ship.
