Since 1 July 2026 every crypto platform serving the EU needs a licence. For you as a user that means no ban, but this: without a licence you lose protections — segregated assets, liability, a complaints route. Which platforms are in the register, what happens to DeFi, USDT and your own wallet, and how to check a venue.

A chart claims to "prove" liquidity leads crypto. The thesis is serious — the chart isn't proof. What it shows, what it doesn't, and how to test it honestly.

zBTC runs, it's multi-chain, the product delivers — and the ZEUS token fell about 98%. How does that fit, and what does the road ahead look like? A sober tokenomics case study.

The "hacked again" reflex is wrong. What the Polymarket case actually shows — and the two places where crypto genuinely is harder.

We ran the same RSI/SMA crossover across the top 50 coins and the top 50 US stocks — identical rules, identical window. On crypto it beats the buy-and-hold benchmark 80 % of the time; on stocks, 4 %. Why a trend-following strategy works in one market and bleeds in the other.

The 200-day line is the most-cited trend filter in markets: invested above it, out below it. We tested it as a standalone strategy across 110 assets. The result is not one-size-fits-all — on crypto it beats Buy & Hold on return AND drawdown AND Sharpe; on index ETFs it gives up almost no return while nearly halving the drawdown; on single stocks it works poorly. An honest map of where regime timing pays and where it doesn't.

The perpetual is crypto's most-traded derivative — a future that never expires. To stop it drifting from spot, longs and shorts pay each other funding. How it works, who's really on the other side of your leveraged long, and why funding flips whole strategies.

A new strategy is live: Gerald Appel's MACD from the 1970s, now fully tunable (default 12/26/9). Two trade modes — classic signal cross or histogram flip — give you a reactive and a confirming variant from one indicator.

A new strategy is live: BB+RSI combines two classics into a strict mean-reversion setup. BUY only when price is at the lower Bollinger band AND RSI is oversold — two conditions, fewer false signals. Pro+.

A new strategy is live: two configurable EMAs cross — BUY on the upward cross, SELL on the downward cross. Default 9/21, faster and more tunable than Golden Cross. Plus optional volume- or price-confirmation filter to fight whipsaws.

The Take-Profit / Re-Entry strategy combines two simple rules: sell when your target gain is reached, re-enter when price drops enough from the post-sell high. No indicator noise — just price and two parameters.

Grid bots are marketed as "low-risk" and, with AI, as a source of "consistent profits." We checked the claims against the mechanics: a grid earns on sideways oscillation, not trends — and "always trading" means trend-chasing. A fair breakdown, plus how to actually evaluate a grid bot.
