Gold is very dense. There are physical constraints making it difficult to transact large amounts of it.<p>Even though humans can constrain the transaction throughput of bitcoin, bitcoins or other crypto currency, will probably, eventually, converge on a solution where the possible tx rate is far larger than we can use. Tx rate limiting won&#x27;t be a feature of any crypto coin that survives. You&#x27;re just observing the effects of imperfect initial engineering. I wouldn&#x27;t draw broad conclusions about the impossibility of successful cryptocurrencies based on this current limitation.
