https://en.wikipedia.org/wiki/IOTA_(technology) Has now climbed above Dash to be the fifth largest coin by "market cap", behind Bitcoin, Ethereum, Bitcoin Cash and Ripple. https://coinmarketcap.com/currencies/iota/ https://twitter dot com/ThinkFinance999/status/938012654161027072 Well, IOTA's tangle does (superficially) seem superior to blockchain. If thisis so, one crypto is already obsoleting most others. .
Americans will have to buy iota at https://www.binance.com/ as Bitfinex will not open an account for US citizens.
UPDATE: At the time of writing, according to Worldcoinindex, IOTA has moved up to number four on the charts, surpassing Ripple. IOTA $9.39 billion (at a price of $3.3799) Ripple $9.16 billion (at a price of $0.2375) (Coinmarketcap has slightly different figures of $9.53 billion for Ripple and $9.46 billion for IOTA.) Either way, what is known for certain is that IOTA's volume has been huge in the past 24 hours, as noted by just21 above. .
I'm trying to work that out myself. The tweets from https://twitter dot com/ThinkFinance999 might be a good starting point. Maybe also https://www.reddit.com/r/Iota/ .
