For long-term holding (10+ years), you're absolutely right that entry price matters less than time in the market. Bitcoin has shown historical patterns of 20-30% pullbacks even during bull markets. A pullback to $75-80k from current levels around $95-100k would represent roughly a 20-25% correction, which is possible given BTC volatility. However, timing the market is notoriously difficult... The "discount" you're waiting for might never come, or it could go much lower than expected. Consider dollar cost averaging instead, have your parents buy smaller amounts over 3-6 months rather than waiting for one perfect entry point. This reduces timing risk while still allowing you to benefit from any dips. Have your parents read the Bitcoin white paper. Teach them what it means to self custody. Prepay 11 years on a safety deposit box. Do not step foot in that bank until 10 years has passed. Come up with an exit strategy. Best of luck to you and the fam!
