BTC paper-trade idea

Slate reviewed daily at 6 AM, 12 PM, 6 PM & 11 PM CT · fills, targets & stops tracked every 30 min

No active idea for BTC. No setup (reviewed evening Oct 21). ~84.4K is pressing the 84.8-86K resistance band after a short squeeze; a long here is late and a pullback buy at 82.5-83K with a stop under 80K is only ~1:1 to 86K. Wait for a clean retest or a daily close above 86K.

Every idea is tracked against 5-minute candles and logged, losses included. See the track record.

How to buy BTC (Bitcoin)

In the US

Coinbase / Coinbase Advanced (BTC-USD)
Kraken (BTC/USD)
Uphold (BTC)

Outside the US

Bitunix (BTC/USDT spot and perpetual futures)
Kraken in many countries

Pick an exchange that lists BTC where you live. Compare fees and the trading pair before you sign up.
Create an account and verify your identity. Regulated exchanges ask for ID and proof of address before you can deposit.
Fund it. A bank transfer (ACH/SEPA) is usually the cheapest; cards cost more.
Buy BTC on the spot market (BTC-USD). A limit order at a level you chose (see the support levels above) avoids paying the spread on a market order.
Decide where to keep it. For long-term holdings, consider moving it to your own wallet (below). When you withdraw, pick the Bitcoin network your wallet supports: sending on the wrong network can lose the funds.

Self-custody: keeping BTC in your own wallet

Keep long-term holdings in a hardware wallet like Ledger. Coins on an exchange are an IOU from that exchange. A hardware wallet keeps the private keys on a small offline device, so you approve every transfer yourself. Before you send BTC to any wallet, check that it supports the Bitcoin network, write the recovery phrase on paper (never in a photo or a cloud note), and send a small test amount first.
