so you are looking to spend up to 1k for "fire" which sells locally for $250 - $300 an ounce.
lets say a vendor has that "fire". it looks the part, the reviews are good, the vendor is solid.
off the top of your 1k investment youve got to add at least 5% in fees associated with getting coin but more like 10% if you care about how you get them. Then you add another 5% minimum for tumbler fees. Youll break the tumbler deposits up because only a gobshite sends their money in bulk to an anonymous laundering service.
lets be really liberal with our numbers and say that between getting coin, tumbling and volatility youve got $1200 invested in your "fire".
if your market dictates a rate of $250 per ounce then your $1200 dollar investment comes with a bit of work as you break it down into halves and quarters. With liberal numbers applied youve got to sell all sixteen quarters to make $350 profit. Now we know not all 16 quarters are going to make it onto the sales floor. Assume you take just one small quarter for yourself, for the effort, for the people. now you are down to $250 profit generated from your $1200 investment.
You can fudge the numbers up or down but the costs ive mentioned are real.
considering that the evolution of your endeavors will span a minimum of 5 days if youve got a lot of clientele waiting on your doorstep. a little bit longer if you dont or your order arrives between paydays. variables and all that.
to me that seems like a very slim profit margin with no long term success possible. You cant bring a product into a market with the same or slightly better quality when the market has the supply to set an deflated rate. That $250 to $300 an ounce price is pretty much the standard. Its the same price indoor hydro was going for on multiple college campuses 20 years ago.
your profit margin is fucked and you will have to sell twenty units (qps) at maximum profit just to hire a plea deal lawyer to get you out from under the penalties if your caught.
but worse than getting caught in some ways is getting scammed. scroll through any market forum or this reddit to read those sad tales of woe where little johnny sent some 5 star vendor 1k anonymously and the product never arrives. Thats a big, stressful hit for most people not to mention the negative emotions, clients going elsewhere, etc.
tldr: shitty profit margins, logistics and risk correlate into this being a questionable way to make a buck.
just my humble opinion...
