Bitcoin has come under pressure today amid sharp gains in alternative currencies, but the charts are showing no signs of panic.

Having clocked a high of $15,394.99 at 02:14 UTC today, CoinDesk's Bitcoin Price Index fell to an intraday low of $14,225.17 at 09:14 UTC. At press time, bitcoin was trading at $14,500 levels. Quite clearly, the 2 percent depreciation in the value shown by data source CoinMarketCap is largely due to the decline seen between 02:14 UTC and 09:14 UTC.

Meanwhile, cheaper alternative currencies are strongly bid. For instance, Ripple's XRP token has set a new all-time high of $3, having appreciated by a hefty 31.63 percent in the last 24 hours. Furthermore, prices of cardano (ADA) and stellar have jumped at least 20 percent each, while NEM (XEM) has appreciated by 46 percent.

An argument could be put forward that investors are using the BTC to accumulate alternative currencies, given the sharp gains in the XRP/BTC, ADA/BTC and XEM/BTC pairs.

Amid what some are calling an "altcoin bubble," it remains to be seen whether money will pour back into BTC once the valuations of the alternative currencies start to look overstretched.

Currently, the charts suggest BTC is down but not out and is holding onto bullish territory.
