It’s been an amazing year for crypotcurrencies, which serve as a digital method of payments and, in some views, as an alternative to gold and other safe haven assets. While bitcoin has garnered the lion’s share of the headlines, there are now 36 cryptos that have market caps greater than $1 billion, according to CoinMarketCap. If bitcoin’s value came to 10 percent of the total $100 bills in circulation — $110 billion divided by 17 million bitcoins — that would approximately produce the $6,500 bottom end of the range. Using 33 percent would get the $22,000 upper range. Someone said the point near 14,000 is the fair price to hit. And that the question waiting for answer.
