I play mainly online. Over 20+ years I've played everything from $1 MTT's to the Sunday Million when it had a $215 buy-in. For me personally I've found the sweet spot at $5-$50 buy-ins. While I maybe only a rec/hobby player time matters so micro buy-ins of $1-$4 even when one final tables or wins isn't good value for time spent as I play 7-8+ hour long blind level MTT's. Micro buy-in MTT's also play a lot like
freerolls where no one really cares about the stakes and will shove all and call with almost nothing(way to many callers every hand) which makes it almost impossible to get thru larger MTT fields which I also prefer.
I have played a decent number of times in live MTT's with buy-ins from $50-$1000 and done well. Being a small province of only around 1.2m population we don't get many larger buy-in MTT's then that and don't really get many $1000 buy-in MTT's.
Cheers!!!
