@DatingDisastrously
From my (reasonably short so not immense ) experience with bumble my strategy was to just send a “wave” emoticon at most/everyone I matched with
as some just wouldn’t reply or chat would fizzle out very soon? So it was a waste of time doing crafted messages.
I got offered the deal where you could see all your possible matches for a few days and I video dated someone in another city but we didn’t continue.
I had two meets - one who I’m still seeing, one who was a really good meet but we didn’t push through as I became intimate with someone else. Both seemed attractive solid guys, just no time to meet women IRL.
Few other likely potentials but we didn’t get round to meeting. Usual sprinkle of married weirdos and hookup guys 
I really wouldn’t worry about things like frequency of reply etc - I just tried to treat every new interaction like I was dealing with a new person and be polite and positive. And my meets were the same personality.
if someone is scanning the site judging people for how much they reply/how often they are on etc then they’re just rude and judgemental and will neg or nit-pick whatever!
I mean everyone is on the site has created a profile and signed up to meet people? No-one is too cool for the site if they’ve actually made the effort to join it?
With smartphones most people have and use the ability to check messages constantly.
some guy playing “hard to get” or pretending they’re not looking to meet someone and wanting to meet someone who also “plays hard to get” is just weird and immature!
