What a small top-up buys#
Enough residential traffic to run a real crawl for a day, a single ISP address or mobile device for 24 hours, or a datacenter address for a month: the point is to test against your actual target, not a demo page.
Network fees#
With cryptocurrency, the sender pays the network fee, which varies by coin and by congestion. Low-fee coins (Litecoin, Tron-based USDT, Solana) make small top-ups practical; a Bitcoin fee can be a large share of a small deposit at busy times.
How it works at ProxShift#
ProxShift's minimum top-up is $20, enough for a few gigabytes of residential traffic or a 24-hour ISP address; there is no free trial, and unused balance stays available.
