BTC, ETH, SOL and XRP 15-minute rounds: how they compare

TickTilt shows four coins side by side: Bitcoin (BTC), Ether (ETH), XRP and Solana (SOL). This guide covers what the rounds have in common and what tends to differ.

What's the same

• Same clock. Each round covers a 15-minute window, and a new one follows the last.
• Same settlement idea. The final 60-second average of a CF Benchmarks real-time index is compared to the 60-second average before the window opened. At least the target means Up; below means Down. See how rounds settle.
• Same payout. A winning contract pays $1.00. The same fee formula applies unless a series lists a different multiplier.

What differs

The index. Each coin settles on its own CF Benchmarks index, named in that market's rules. For Bitcoin it is the BRTI. Always check the rules for the coin you're looking at.

Price scale. BTC trades in the tens of thousands of dollars, XRP around a dollar or a few. A "$20 lead" means a lot for some coins and nothing for others. Compare leads as a percentage of price, not in dollars. TickTilt's estimate for each coin does this.

How jumpy the coin is. Smaller coins often swing more, in percentage terms, over a few minutes than Bitcoin. A bigger swing means a lead is more likely to flip before the close. This changes over time, so don't assume yesterday's pattern holds today.

Market depth. Bitcoin rounds usually have the most trading activity. Thinner markets can have wider gaps between buy and sell prices, so the price you can actually get may be worse than the headline number.

How TickTilt reads each coin

For BTC in the last four minutes, TickTilt uses its own history of how often a lead of a given size held on, based on Kalshi's official settled results. For the other coins, and for BTC earlier in a round, TickTilt uses a simpler estimate: how far the price is from the target compared with typical price movement in the time left. It also uses Coinbase prices as a stand-in for the settlement index. Both are rough guides, which is why TickTilt shows leads as probabilities, not certainties.

A plain checklist

1. Read the market's rules and its index.
2. Check the target and time left.
3. Think in percentages, not dollars.
4. Remember the price already reflects the crowd's view, and fees raise the break-even.
