If this is what is needed for every holder then we're not ready to welcome global adoption because many people won't have the time to start doing that. I know we always say we should be incharge of the security of our finances but if we have to go through this courses to achieve that, It would be a failed mission. I have nothing against cyber security as they'll definitely be useful to anyone that takes them but to hold bitcoin doesn't have to much of a trouble. One thing I noticed in the industry is that those claiming to know it all (when to buy, sell, hold etc) don't get profits but the average users that just buy and store his Bitcoin in a secured location always come out profitable.

If you have the time and money to afford a cyber security course, take it but if you don't then just make sure your investment are secured in the best possible way because hackers will not stop at nothing to steal your Bitcoin if they find out you have some that they can steal. A paper wallet or a non custodial decentralized wallet is fine to use to store your Bitcoin and you just relax and let the market do its magic. You can come back in few years and your investment would had yeild great results (profits).
