The likelihood of losing your seed phrase depends solely on how well you store it. This is a completely controllable situation with the right approach, but it is not the only risk when investing in Bitcoin. That is why I say that the risks of investing in Bitcoin are much greater than losing your seed phrase.

The risk of losing your seed phrase can be avoided altogether by buying a Bitcoin ETF rather than native Bitcoin, but that doesn't make such investments risk-free. Your investments are still subject to risks—high volatility, tighter regulation, possible protocol errors, hacks, competition with other blockchain technologies. These risks should not be forgotten either.
