Inspired by https://money.stackexchange.com/q/99754/25694 What would prevent me from investing $1,000 for a month, pulling out, investing with a different scammer, rinse & repeat? This question is not specific to the inspiration question but just in general what stop-gaps do scammers implement to prevent me from scamming them? Are there legally binding stop-gaps such as contractual clauses which state something like "Must invest for 12 months minimum. Early withdrawal forfeits all interest and costs 20% of principle." Does anyone have samples of real scammer investment contract clauses which could be considered as stop-gaps?
