Also those ppl that bought btc like around that time or before it, was the exchanges the most popular place to keep btc? Then electrum was pretty close up there? What other wallets were available similar to electrum at the time?
Actually, Bitcoin Full Node (
Bitcoin Cli, now Bitcoin Core) at that time (
2011-12) is the best way to store bitcoins since the Blockchain isn't that huge to be a problem for most (
geek, technical or fan-base) users.
But mostly all late-comers (
including me) were using bitcoins in online "
game/gambling" that offers free bitcoins via faucets and didn't even cared about its value at that time, it's something like this: you can play games for free/low-cost using a new/unknown digital cash.
Most bitcoins were stored (
or forgotten) in those High/Lo & Faucet sites.[

About other available clients, I'm not qualified to answer since I started trading Crypto a year before I joined BCT (
not too late before the big HYPE).
Also was security with electrum pretty good back then when it came out?
Not sure but, Electrum's security today isn't really
that reliable since it requires a third-party host/node.
That's why they've added the newbie-friendly 2FA option with additional cost in exchange for security in 2015(?), or anyone can set-up his own 99% safe
cold-storage wallet.
