> Fidelity offers HSAs for employers and, as of November 2018, individuals.[36] Individual HSAs have no account opening or transaction fees.[37] In a favorable review of the Fidelity HSA's features, the The Finance Buff wrote: "No other HSA provider comes close to what Fidelity offers."[38]

I would go to Fidelity.com/toa and start a transfer of assets from your current HSA. If it is an employer sponsored HSA where your employer contributes to it, then leave $25 to avoid it getting closed. But every year, move the remainder to Fidelity and invest the remainder like any other IRA.
