An alternative to WordPress’ 100 year plan

Introducing the 100-Year Plan: Secure Your Online Legacy for a Century

Assuming it’s a .com, renew for nine years (the maximum allowed by Verisign anyway) for < $100. Keep the remaining $37,900 in a savings account and reinvest the $1500/yr of interest into annual renewals and alternative forms of “securing your legacy”.  Even if Verisign continues to inflate prices at the current rate, you’re looking at $62/yr .com renewals by 2050. You can probably hedge the risk of price increases outpacing your returns by investing in Verisign and GoDaddy?
