What Is Cryptocurrency? Which Coins Should You Buy Now? A Beginner’s Guide to Crypto Investing and Trading
Crypto Market Update
TradingKey – On November 30, 2025, the Federal Reserve announced another 25bps rate cut, sparking a rebound across digital assets. Bitcoin (BTC) reclaimed the $110,000 level, helping investors recover from the panic triggered by the “1011 Black Swan” crash.
That October 11 event, driven by a U.S. government shutdown and escalating U.S.-China trade tensions, wiped out over $400 billion in market value. Bitcoin plunged 17%, major altcoins dropped over 30%, and more than 1.6 million traders were liquidated, totaling nearly $20 billion — the largest mass liquidation in crypto history.
What Is Cryptocurrency?
Cryptocurrency is a digital asset secured by cryptography and powered by blockchain technology. It is decentralized, meaning it operates without a central authority, and is transparent, borderless, and resistant to censorship.
The concept was introduced in 2008 by the pseudonymous Satoshi Nakamoto, who published the Bitcoin whitepaper: “Bitcoin: A Peer-to-Peer Electronic Cash System.” In 2009, the Bitcoin network went live, and the first BTC was mined — marking the birth of the crypto era.

Which Coins Are Worth Watching?
For beginners, focus on high market cap coins like:
- Bitcoin (BTC)
- Ethereum (ETH)
- Ripple (XRP)
- Binance Coin (BNB)
- Solana (SOL)
These coins are widely traded, supported by major exchanges, and have strong community and institutional backing.
From a regulatory catalyst perspective, coins like SOL, XRP, LTC, ADA, AVAX, and DOT are worth watching. The SEC may approve spot ETFs for these assets in 2025–2026, potentially unlocking billions in institutional inflows. Notably, SOL, XRP, and ADA are part of the U.S. strategic crypto reserve, signaling long-term policy support.
