I've ordered my entire computer system with BTC as well as most of the items in my new house. I have used amazon, scan, argos, primark, sweet shops and a few others. There is plenty you can buy with bitcoin.
As far as phore goes, in my eyes, it's currently in my top 3 coins. The dev team are open and honest, trading volume is okay, price is very stable (Can't stop people buying and selling). A better exchange would bring some welcome attention but the continued hard work by the team here will bring rewards.
There are a lot of coins out there that have dropped in price, this isn't anything new in crypto or any market for that matter. I purchased some phore at around 40k sats and have them staking. When BTC goes on it's wild swings, everything moves with it, even the ETH supporters thought ETH would stay higher than it is.
How do you buy on amazon with BTC?
I've ordered all of my PC parts as well with BTC but besides that there's nothing you can really buy directly with BTC (at least here in Germany).
You can get a BTC Creditcard, that's the only way to spend BTC "directly". But than I can as well sell the BTC for € and transfer it to my bank account with nearly zero fees. So in the end .. USD is what counts. Even when you buy directly with BTC. The price stays in USD or EUR and the BTC amount charged to buy varies .. Even though the PHR to BTC price is "ok" this is nothing that would bring some benefit to your life ..
I really think PHR is great and has a huge potential. I bought my PHR at 0.3 $ each and have let them stake ever since. But now I regret haven't sold them at 9$. If I would have done so I would have been able to buy two complete PHR MNs by now .. (Because PHR dropped harder than BTC)
