The whole issue of wallet security has to be addressed this year if the crypto community wants mass adoption of the technology. I created a metamask wallet on PC and it crashed after installing it. Thankfully there were no tokens in there.
I am concerned by your comment about Ethereum based in-browser web wallets. I would like to invest in several coins that run on the Ethereum network such as PPT.
Where can you store such coins if not in an Ethereum based in-browser web wallet?
