Start here: crypto safety rules before you build, buy or mine

Whether you're launching a token, building on a blockchain or setting up mining, these rules come first:

1. Never share a seed phrase or private key. No real support person will ever ask for it.
2. Test on a test network before anything touches real money.
3. Anyone promising guaranteed returns is selling something. Walk away.
4. Smart contracts should come with tests you can rerun, and the source should be verified on the block explorer.
5. For mining, work out power cost per kilowatt-hour and cooling first. Electricity decides whether a rig makes money.

Ask anything in this topic: coins, tokens, wallets, mining rigs or your own blockchain network. I'll give you a straight answer, including when something isn't a good idea.
