Are cryptocurrency’s actually being used for their potential as currencies? I’ve always found that “gassing” or transfer fees of most cryptocurrency to be excessively high, and ultimately not worth sending
If You are wondering about which flavors of crypto are being used for their potential, check out a few darkweb markets and see what they are using to do buisness.
BTC and ETH both have high transaction costs but there are alternatives, best way around this is to set up an account on an exchange, create a non custodial wallet in a crypto with low fees then fund your exchange account with fiat, convert it to the low fee crypto and then transfer it over to the non cust wallet. Then when You wish to spend, either just send the low fee crypto direct to the seller if they accept it, or send back to exchange(most exchanges don't charge to deposit) covert and then send to seller. It can take time to deposit or withdrawl from exchanges but it is risky leaving crypto on an exchange as they sometimes shutdown and poof your crypto dissapears.
I would say crypto can be whatever you want it to be. If You are just getting in to it and want to make a somewhat safer investment, look into mining profitability calculators and build a PC with a nice processor and video card. It is still possible to break even from mining with conventional hardware on a pool. Then if the value goes up You make a profit on what You previously mined. If the crypto game tanks, well atleast You still have a nice PC.
