ETH for smart contracts, SOL for speed, some DeFi blue chip. Then I asked what I'd actually lock away for 20-30 years without touching.
BTC is the only one where the value proposition hasn't changed since day one. Fixed supply, no foundation that can pivot, no roadmap that can fail, etc. Everything else requires you to be right about technology bets that haven't played out. BTC just requires you to believe scarcity has value, which is a bet humans have been making forever. I'd just keep it earning interest on a platform like Nехо or Krаken for the next 20-30 years, and voila, my kid will have a tuition fund.
Custody planning is also solved in a way nothing else is. Inheritance planning for a protocol that might not exist in 15 years is a different conversation. So what would you pick?
