Bitcoin
since 2009 · UTXO, its own networkWhy Bitcoin, who needs it, and how this network’s rules differ from the rest — short and to the point.
Four Bitcoin rules worth knowing before you send
Not abstract “crypto risks,” but the rules of this network. For each — what happens, and how Mitilena shows it before the Send button.
Fee is for block space, not for the amount
You pay for transaction bytes, and the price per byte changes every hour with mempool load. A $5 transfer can cost $5. If the wallet “picks the fee for you,” it is easy to overpay three times — or set so little that the transfer sits for a day.
A stuck transfer cannot be cancelled
A low-fee transaction can sit in the mempool for hours or days. In Bitcoin you cannot recall it: until it confirms, the money is neither with you nor with the recipient. So set the fee with a margin up front, not “I’ll speed it up later.”
Three address formats and one BCH trap
bc1q, bc1p, 1… and 3… — all of that is Bitcoin, just different generations. The trap is elsewhere: an old Bitcoin Cash address looks like a Bitcoin 1…, and BTC sent to it goes to an address the recipient may not hold the key for.
Dust: many small inputs — an expensive send
Every deposit is a separate “coin” on the address. A hundred tiny top-ups later leave as a hundred inputs, and the fee for that transfer can eat it whole. Change below “dust” simply burns.
How to send BTC in Mitilena
On Bitcoin — only BTC
There are no tokens on Bitcoin in the usual sense. USDT “on bitcoin” has not been issued since 2023. Need a stablecoin — in the same Mitilena, Tron, TON, Ethereum and Solana sit next to it. Ordinals and Runes are inscriptions on top of BTC: satoshis show on the address as a normal balance, which is enough for holding and transfers.
What Mitilena can do on Bitcoin
What people ask about Bitcoin
How long does a BTC transfer take?
First confirmation — about 10 minutes on average at a market fee. Exchanges credit after one to six confirmations, so from 10 minutes to an hour. The slider in the wallet shows the wait before you sign.
Why is the fee so high for a small amount?
Because you pay for bytes, not for bitcoins. A transfer of $5 and of $5 million weighs the same. Small amounts — in quiet hours, or USDT on Tron: it is in the same Mitilena wallet.
Which address to share: bc1 or 1…?
bc1q. Every exchange accepts it, and sending from it is cheaper. Addresses 1… and 3… are older formats — they work, but the fee is higher. New addresses in Mitilena are bc1q.
Can I hold USDT on the Bitcoin network?
No. USDT on bitcoin (Omni) is no longer issued. For USDT — Tron, Ethereum, TON or Solana: all of them are already in the same Mitilena wallet.
Is there Lightning?
No — on purpose. Lightning needs the key online for every channel update: you cannot put it on a card and sign offline. For small fast payments, Mitilena has USDT on Tron and TON next to BTC.
The transfer is stuck. Can I speed it up?
In Bitcoin you cannot recall a transfer after sending: pick the fee before you sign. In Mitilena the slider shows expected time for each value — set a margin up front if the transfer is urgent.
