What gets confirmed
Transactions enter blocks that must satisfy network rules. Mining helps participants agree record order, rather than merely “creating coins on a computer”.
FinFly Explains / Crypto
What crypto mining is
Mining helps agree transaction history in proof-of-work networks. Bitcoin is the example here; its design should not be assumed for every cryptocurrency.
Why it is competitive
Bitcoin describes mining as a computational competition. Participating does not mean each computer adds blocks on a schedule.
Not every network mines
Ethereum no longer uses proof-of-work. Check a claimed mining service against its actual network, not merely a familiar coin name.
Questions for a seller
FinFly recommends requesting the network, verifiable work, all costs and withdrawal terms. Separate the technology from promised returns; fixed payouts are not evidence of real mining.
Questions
Short answers
Can every cryptocurrency be mined?
No. It depends on network design; Ethereum, for example, moved to proof-of-stake.
