Bitcoin After the Arc Break: The Time Window Opens on 19 August
The arc gave way on 1 August. The path to the inner high-volatility zone at $51,468 is now open — and the new 2.5-year cycle begins on 19 August.
Perpetual futures, copy trading, custody through Fireblocks. What Blofin does, what it costs — and where the limits are.
Blofin is the exchange SonarSignal builds on by default. Here is why — and what speaks against it.
A centralised exchange focused on perpetual futures. More than 350 contracts, leverage up to 150x, plus a dedicated copy trading section with a public leaderboard. Spot trading runs alongside but is not the core.
In futures, 0.02% as maker and 0.06% as taker, falling to zero maker across five VIP tiers. Spot costs a flat 0.10%. For a signal strategy the taker fee matters most, because entries rarely get to wait.
Custody runs through Fireblocks in cold storage, alongside a 1:1 proof of reserves, transaction screening via Chainalysis, two-factor login and passkeys, and an ISO 27001 certificate. That is more evidence than the average in this field provides.
Three reasons. Futures fees are low enough that a signal strategy is not ground down by them. The API is stable enough for automated orders. And we hold a broker account through which we can agree limits and request volumes directly — something you cannot do with an exchange that does not know you.
Blofin is not a European-regulated exchange. There is no deposit protection, and in a dispute German law does not apply. Withdrawals of up to 20,000 USDT a day are possible without identity verification — convenient, but it also means your account is not tied to a verified person.
And leverage up to 150x is a possibility, not a recommendation. At 150x a move of two thirds of one percent is enough to liquidate the position. We run far below that, and so should you.
