Personally, I think that monero might be worth considering as the alt coins. The fact that you can't buy it on crypto exchanges tells me that the establishment sees it as a threat. It's not a good store of value like Bitcoin, but as far as money that you spend, it's worth considering. The value comes directly from its use rather than speculation and wallstreet gamblers. Litecoin and doge should also be worth considering as spendable currency. Bitcoin is always going to be the best option for storing value but when it comes to spending money I think it's a good idea to consider those 3 as the only real "alt coins"

Bitcoin isn't a store of value stop saying random shit lol There is only one real cryptocurrency and it's the one that the state deems an actual threat. That's the signal.

All money is a store of value technically, that is literally what money is. What do you think a savings account is? It's a store of value. My point about Bitcoin is that it's a better store of value. If monero or doge were cash, Bitcoin would be like old silver or gold coins

Kraken in some countries offer XMR. There's one coin I own besides BTC: it's XMR.

No, purchasing power fluctuates. Stores of value include things like antiques, gold. Currency is currency. 1 dollar today is not equal to 1 dollar in a few years. Same can be said for Bitcoin. Bitcoin is not gold, it'll never be gold. Bitcoin is just another currency, traded against other currencies
