In October 2026, attackers emptied wallets that had been set up on Ledger devices from the reseller CryptoBilis. The devices were genuine and passed Ledger's genuine check. Inside the case sat a radio module that read the 24 words off the screen during setup.

The market maker Keyrock says 90 percent of token unlocks push the price down. Counted across 1,247 unlocks since 2021, an unlock does cost something, but not on unlock day. And the bigger loss comes from somewhere else.

The biggest crypto hack in history cost Bybit about 1.5 billion dollars in February 2025. Its customers lost nothing. Thieves give back almost nothing: 3.1 percent of everything stolen. So whether you see your money again depends on who can carry the loss. A solvent exchange can. A bankrupt one cannot, and in your own wallet, it is you. The biggest hacks, how they worked, and what follows for where you keep your coins.

OneCoin, Bitconnect, PlusToken, Celsius, FTX: billions gone, millions of victims. In 9 of the 15 biggest cases, the warning sign was in the offer itself, before anyone paid in: a fixed return, money for recruiting, a source of profit nobody could check. What the biggest scams had in common, how little victims got back, why the fraud of today looks different, and five questions to ask before you deposit.

Ichimoku is usually traded with 9, 26 and 52 and with the rule "only buy above the cloud". Both were tested on crypto from 2018 to October 2026. The cloud rule lowered the result on all ten of today's largest coins, and on bitcoin and ether the traditional numbers did no better than randomly drawn ones. What that means for your settings.

Solana is gaining ground where the future is supposed to be: its share of tokenized securities has more than doubled since early 2025, and BlackRock keeps 43 percent of its BUIDL fund there. But in the third quarter of 2026, 65.7 percent of the revenue of apps on Solana came from memecoin trading, and 1.2 percent from all the long-term fields together. What Solana does, where it really grows, who buys and sells SOL, and how the price has done against bitcoin.

Kaspa delivered: ten blocks per second since May 2025, smart contracts since June 2026. Yet users pay the network about 94 dollars in fees a day, less than Dogecoin, while new coins worth 71,500 dollars go to miners daily. What Kaspa does, who uses it, how its supply works, and why every upgrade so far was followed by a lag against bitcoin.

Staking ALGO pays roughly 5 percent a year. The network takes in about $142 a day in fees, around 170 times less than it pays out. The rest comes from the Algorand Foundation, committed for about 24 months from January 2025. What Algorand does, who really uses it, who holds and sells ALGO, and how the price has done against bitcoin.

Zcash can hide what Bitcoin and Lightning cannot: the amount. Private use grew as fast as the price last year. But per private transaction the market pays ten times what it pays for Monero, and the few who carry that price have stopped buying.

Bitcoin can already hide who gets paid and which coins belong together. It cannot hide how much. Zcash and Monero can, and each pays for it somewhere you should know before you buy.

Venice sells private AI, and its DIEM token pays out one dollar of API credit every day. A DIEM costs about $1,870 on the market, but minting a new one locks up VVV worth about $11,500. What Venice does, how DIEM works, who controls the supply, and how VVV has done against bitcoin.

Every new blockchain on Avalanche used to lock up AVAX: 2,000 per validator. Since the Etna upgrade in December 2024, all 577 active validators of Avalanche's own chains pay about 9,200 AVAX a year combined. What Avalanche does, who uses it, what really carries the token, and how AVAX has done against bitcoin.
