dkbit98: Testnet coins are FREE are worthless!
Talking about testnet-BTC, that coin already has a lot of warnings outside this forum, lucky you weren't given a red label by @dkbit98, in your confidence.
He did the right thing to warn about the dangers of testnet-BTC, as I see it.
The first problem is about testnet-BTC.Operating costs: On testnet, tokens do not have any value. Operating costs on mainnet are higher. Every operation performed on the blockchain requires a fee in the form of a token that has a certain value. examples of these operations include value transfer, staking rewards, or Smart Contract deployment.
Transaction frequency: Transaction frequency is low for testnet.
The second problem concerns the testnet-BTC coin.Fraud method 1: Fraudsters claim that they have some tokens to sell in a hurry, and give very attractive prices. Beginner users are greedy for cheap prices, and after receiving the transferred tokens, they find that they cannot be traded and have no value.
And the third problem is about testnet-BTC, this third is a bad warning for crypto users, if they understand about testnet-BTC.
We are experimenting with testnet-BTC (tBTC). Note that, testnet-BTC (tBTC) is for testing purposes only.
It's worthless. These are not real Bitcoin (BTC) satoshis in your account. Don't be a victim of SCAM as there are lots of people out there to sell tBTC to clueless beginners.
From the three sources and data above, perhaps we should be aware of the dangers that could occur for testnet-BTC users, if they understand what will happen next.
