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.
It's actually true that Bitcoin is one of the most sorted after asset in the world right now, and we are a big fan of it no doubt, but that shouldn't blind our eyes to be wasting our money, by buying something like this that is a total waste, though I haven't gotten up to that level were I will even think of spending on these kind of things, but I would rather invest in something more better, which is real estate, than spending an a crazy amount of money on a stupid thing, just to message my ego.
Lastly, it's very good and logical to do your own research in any investment you want to venture into, so as to be more enlightened on what you are venturing into, because I believe that if a proper research was done, that investor will also sees it from the same angle we are seeing it, which is a total waste, unless he just want to sell it to someone as crazy as he is.
