• Bitcoin fell below $63,000, marking a 1.4% drop in 24 hours, influenced by profit-taking after a recent rally.

• QCP Capital noted options-market activity that suggests a generally bullish mood, but not an explosive move higher in the short term.

• SafePal's SFPlus release boosted its SFP token value by up to 8% over the past week by adding rewards to encourage staking.

Bitcoin (BTC) slid under $63,000 early Tuesday as profit-taking after a weekend rally extended into a second day and weighed on the broader crypto market.

BTC fell 1.4% in 24 hours, CoinGecko data shows, with ether (ETH), BNB Chain's BNB, Cardano's ADA and xrp (XRP) falling as much as 2%. Memecoin dogecoin (DOGE) led majors lower with a 4% slide, while Ton Network's TON – hit by the arrest of the CEO of closely related Telegram – fell 4% to bring seven-day losses to more than 20%.

The broad-based CoinDesk 20 (CD20), a liquid index of the largest tokens by market capitalization, fell 1.5%.

QCP Capital, Singapore-based trading desk, noted an increase in call spread buying while noting the selling of bitcoin calls at the $100,000 level. The strategy suggests a generally bullish mood, but not an explosive move higher in the short term.

A call option gives the buyer the right, but not the obligation, to purchase an asset at a specific price, called the "strike" or "exercise" price, on or before a specific date, called the "expiration." Calls are implicitly bullish. A put option gives the buyer the right to sell an asset at the strike price on or before the expiration date. A bull call spread consists of one long call with a lower strike price and one short call with a higher strike price. Both calls have the same underlying asset, such as bitcoin, in this case.
