that time it worth nothing, and now $WIF worth ≈ $1.2, thats was so fast
imagine buy $WIF back then 
Well, as Bitcoin enters into what they know as the bull run, many coins are getting pumped lately, and one of them is the meme coins.
If you look at the chart of all meme coins, most if not all of them are up more than 50% at least in the past 7 days. Those who choose to hold their meme coins might be on profit currently. As for WIF, I don't know what's the reason for it to pump aside from the fact that meme coins in general are getting hyped "AGAIN".
Your imagination will stay as imagination. You didn't bought don't you? You didn't took the risk back then? I guess we'll just imagine that huge opportunity that we lost.

Well, there are still many meme coins out there, and expect more in the future. Some might be through airdrops like what happened with WEN token.
