What to keep in mind for BTC
BTC is the least volatile of the majors but still routinely moves 5–10% in a day and has drawn down more than 70% in past bear markets.
On-chain BTC fees are paid per byte of block space and spike when the mempool fills, so plan withdrawals around quiet periods; exchange trading fees usually dwarf them for small positions.
A backtest is one path that already happened. It shows what this plan produced through the exact sequence of prices BTC went through — not what a similar plan will produce through a sequence nobody has seen yet.
