learn / exchanges
Know what you sign up for.
An exchange is a company holding your coins on its books until you move them. That is fine for a first purchase if you know the trade.
- 01Who holds the keys while your coins sit there.
- 02Whether it is licensed where you live.
- 03The fee you see, and the spread you do not.
learn / yield-staking
Read the risk before the rate.
Staking locks coins to help secure a network. The reward is real, and so are the costs: time locked, penalties, and whoever you trust to run it.
- 01How long until you can get the coins back.
- 02What slashing is and who it hits.
- 03Where the reward actually comes from.
learn / nodes-validators
Running one is a job.
A node keeps a copy of the chain and checks it. A validator also signs. Both need uptime, updates and careful key handling.
- 01Hardware and the uptime you can promise.
- 02Signing keys kept apart from withdrawal keys.
- 03Never the same key on two machines.
learn / depin
Is anyone paying for it?
DePIN networks reward people for running hotspots, storage or compute. The question that matters is whether real customers use what you provide.
- 01Real paid demand, or token rewards only.
- 02What the hardware costs you up front.
- 03What happens if rewards are cut.
learn / basics
The base layer, in plain English.
Wallets, seed phrases and the scams aimed at beginners. Diversify, do not gamble. Use AI to quiz yourself until you can explain it back.
- 01Not your keys, not your crypto.
- 02A seed phrase never goes into a website.
- 03Anyone promising returns is selling something.
FEATURED GUIDE
Exchange Comparison: Find What Fits You
Three kinds of places to buy crypto, side by side, judged by what matters before your first deposit: who holds the keys, what happens if they fail, and the costs you only notice later.
| Question | Custodial exchange | Self-custody wallet | Broker or payments app |
|---|---|---|---|
| Who holds the keys | The exchange | You do | The app, usually |
| If the company fails | You may wait in line as a creditor | Nothing changes, if your keys are safe | Depends on its terms; read them first |
| Moving coins out | Yes, to a wallet you control | They are already yours | Sometimes limited or not offered |
| How you get in | Account and ID check | A seed phrase you must protect | An account you may already have |
| Costs to watch | Trading fee plus the spread | Network fee, swap fee and slippage | A spread built into the price |
| Fits when | You want a bank on-ramp and support | You are ready to hold your own keys | You understand you may not hold the coins |
