That’s the hard part - you have to have enough capital for your gains to mean anything. That’s why they call a small stack a suicide stack - you could 10x $300, but you’ll want to kill yourself for not putting in the other $3000 you had.
There are a few “tells” that a shitcoin can be promising - if people are fudding it before a pump, if the coin’s telegraph group doesn’t seem too scammy, if it’s still low market cap but lots of interest... the main thing is doing your research (which is gay) and finding a comfy coin with decent team (only whites) and alright looking usefulness and tech. Then shill the fuck out of it once you have your bags.
Pump and dump schemes, mostly, so be very careful and do not jump on any mooning coin until you have a few months experience under your belt.
Shill.watch/biz/ is a good tool to see what is being hyped and for how long (pro tip: it’s usually over once there are 5+ threads about it)
