The main problem in early stages will be
A lot of people knowing each other driving the price of a few specific items and creating higher prices for them… then a unknowing person buying at a to high price for a worthless piece being stuck to it… but yeah DYOR and buy what you deem worthy I guess
I think apart from the items that we often use in everyday life, only Bitcoin is more worthy of attention and continuous purchase and this can be done by people who don't like keeping cash in their own wallets. DYOR is necessary because it will lead everyone to think independently about what they want to buy. But in the end there are always many people who are willing to admit Bitcoin as the best to buy even though they have previously spent more time doing research on anything in order to find something more worthy.
