In time of protracted correction, one might think that the $20,000 mark that bitcoin's price reached in December last year was the top price for a cryptocurrency. If one, however, examines CoinMarketCap more carefully, they will find out that there are coins whose prices are much higher.

Bit20 (BTWTY) — $766,995

Token BTWTY—the BitShares exchange's index fund—is the most expensive crypto asset presented on CoinMarketCap. It comprises bitcoin and the 19 most prominent altcoins (except for ripple) which are listed on the exchange. Creators consider ripple's blockchain not really decentralized and excluded it from Bit20. On the 21st day of each month, Bit20 runs an algorithm to create the new composition of the index, which adds new positions and rebalances those already existing. One can buy a portion of the token, but the procedure is quite complex. There's a special tutorial.

Project-X (NANOX) — $288,910

Coin Nanox had a one-time emission and is traded only on the exchange Yobit. Besides, there is only a small portion in circulation—0.078264 NANOX. Creators of the project have preserved their anonymity, but some users are inclined to think the token was issued by the owners of Yobit themselves.

42-сoin (42) — $60,826

42-coin has a limited supply of 42 units. The coin is traded on exchanges Cryptopia, Livecoin, and Trade Satoshi. In 2014, 42-coin's price was 1,197 BTC or approximately $1 million at the time.

We asked Dinar Semenov, a crypto trader with five years of working experience at Otkrytie.Broker and Sberbank's investment department, why this coin is not as popular as bitcoin.

"Founders claim their goal was to create a rare digital asset akin to rare-earth metals. But it has no practical meaning. Besides, 42-coin is barely mineable because of the algorithm making it drastically harder to create new coins. The fact that the first coins of the project were most likely created by its owner does also raise a red flag. It would definitely bring in a lot of manipulation, and that's why we see such a high price," Semenov explained.

BitBTC (BITBTC) — $9329

This derivative product based on bitcoin is traded on the BitShares platform. The value of this asset is attached to bitcoin, but can also differ from the main cryptocurrency.

Russian Miner Coin (RMC) — $8305

RMC tokens have a finite supply; there are currently 1,500 tokens in circulation. Tokens like this are issued for the internal community of investors and offer certain privileges. The Russian Miner Coin community allows its community members to exchange the tokens for the company's latest development—processor Multiclet running on the eponymous chip, which is designed to increase the mining efficiency by ten times, and a new-generation bitcoin miner Sunrise. At the same time, what the team plans to do is not enter the world's leading crypto exchanges but develop the project after having raised additional funds.

BT1 (CST) — $18,273

Despite the high nominal rate, BT1 (CST) does not have market capitalization and trade volume, which can be confusing for beginning crypto investors. In this case, everything is pretty simple: the token represents one of the two pairs of futures contracts issued by the exchange Bitfinex. It allowed the exchange's traders to speculate on the potential activation of the SegWit2x protocol. The latest transaction, according to CoinMarketCap, occurred on January 10, 2018.

Does it make sense for an average crypto investor to buy into the most pricey cryptocurrencies?

"Buying any of the tokens mentioned above (except for those having no trade volume) is possible on the exchanges they're listed on, and one can make money from them just like from any other cryptocurrency. For that, one needs to focus on analyzing the project itself and the overall market situation. With that, however, come extremely higher risks, as prices of such tokens with limited emission are often artificially driven up over a certain period. Although there are no clear reasons for that, the effect of a growing asset appears, which attracts more and more investors," Semenov concluded.
