    The Bitcoin-mining program I downloaded no longer launches on my Windows 10 machine; the .exe flashes for a second and closes. Rather than trying to patch the old binary, I want a fresh, working executable built from the same source features so I can get back to mining without hassles. Here’s what I know so far: • Original purpose: solo/pooled Bitcoin mining, not a wallet or trading tool. • Platform requirement: Windows 10 (64-bit) with normal UAC settings—no awkward compatibility-mode workarounds. • Current codebase: unknown; I have the legacy installer, some DLLs, and a handful of config files. If reverse-engineering is needed to recreate functionality, that’s fine by me as long as the final product is clean and safe. What I need from you: 1. An...

    Miningcore Setup Guide for Ubuntu

    Dhibitishwa

    I’m looking for a clear, step-by-step walkthrough that lets an intermediate Ubuntu user (me) bring the very latest Miningcore up on Ubuntu 24.04, fix the “: Object reference not set to an instance of an object” crash I’m hitting on start-up, and add a single coin with three dedicated stratum ports: • low-diff for CPU/Nerdminer • mid-diff for Lucky miner or older ASICs • high-diff for the newest ASICs and big rigs Here’s what I need: 1. Prerequisites and exact package list, including dotnet, redis, postgres, firewall rules and any kernel tweaks. 2. Git pull / compile instructions for the current Miningcore release, plus the settings that prevent the NullReferenceException. 3. A complete (or split config) that introduces one coin o...

    USDT Purchase Guide – $100

    Dhibitishwa

    I’m ready to purchase USDT for the first time and I’d like someone to walk me through the complete, step-by-step process from funding my account to seeing the tokens in my wallet. I haven’t committed to a specific exchange yet, so you’re free to suggest Binance, Coinbase, Kraken, or any other reputable option if it makes the walkthrough smoother. Here’s what I expect from you: • A real-time session (voice, video, or live chat) where you demonstrate each step and answer questions as we go. • Clear explanations of deposits, order placement, withdrawal to a personal wallet, and any security points I shouldn’t overlook. • A concise summary afterward so I can repeat the process on my own. Once the transaction is successfully completed a...

    We’re launching a new private crypto project and forming a circle of alpha callers, crypto pros, influencers, growth drivers, and more to help scale it. We’ve been building AI, software, hardware, and advanced private systems since 2019 in the United States, and now we’re moving that power into Crypto/Solana/Raydium ecosystem to diversify our portfolio. I have a development team, designers, researchers & analysts. What can you bring? Our goal is to create a small , tightknit, close circle to build this new team and generate real capital together.

    I’m running a small dApp on Ethereum that connects through the library. A recent update introduced smart-contract bugs—functions are reverting and expected events never fire—so the app is effectively stuck. I need a Solidity-savvy developer who can jump in right away, locate the root cause, patch it, and redeploy a clean contract without breaking the existing front-end integration. Key tasks • Audit the current Solidity codebase in my GitHub repo • Isolate the bug and propose the safest fix • Update tests (Hardhat) and prove the fix on a public testnet • Supply the patched contract, migration script, and a concise changelog Turnaround is ASAP. If you can pinpoint and resolve issues quickly, please reach out with your estimated timefram...

    I’m looking for a seasoned crypto trader to help me build a solid, actionable trading plan for USDT pairs. My focus is on both day trading and swing trading, but I want the backbone of the strategy to be smart, disciplined risk management rather than guesswork or “gut feel.” Here’s what I need: • A clear, step-by-step framework for identifying high-probability setups on the major exchanges I already use (Binance and OKX). • Precise rules for position sizing, stop-loss placement, and profit-taking that keep my maximum drawdown within agreed limits. • Guidance on the technical indicators best suited to short- and medium-term trades—think moving-average crossovers, RSI, or ATR-based stops—plus how to combine them for stronger confirmati...
