Should I Sell After 4h When I Buy Onchain?

I've been exploring DEX for a while now and I've had my fare share of losses amongst the gains... It wasn't easy getting started setting up and stuff... After getting rug pulled a few times, I had to change my approach and do more DYOR and it did help in snipping and turned it around after a while...

Whenever the market is red, usually search new ways to earn and on Sunday I saw a chart of how much profit can be made if you buy early on The new Bitget On-chain platform early and sell after 4 hours with discipline...

I have done the calculation and If a user had bought every token launched on Onchain during the first week (April 8–13) with a fixed amount of $10 each (total capital: $150), and sold each one exactly 4 hours later, the overall return would have been 50.28% (net profit of $75.42).

things cant be this smooth all the time but i am just curious... there is a new token $TROLL on there ans i want to start with it...

Is it worth it to sell off at 4h mark or do I adjust my own time to like 5h and try my luck?
