However, I favour a very aggressive trading strategy (possibly not a wonderful idea, but hey, my money

), and I'm being draw to the idea that it's much easier for a $0.01 coin to go to say $0.05, than it is for a higher market-cap asset like BTC to go from 10K to 50K.
That is somewhat of a fallacy, of course. You are making some hidden assumptions. You are assuming that the alt coin will eventually be as big like Bitcoin. You are assuming that the supply of the alt coin is cheaper is the same.
no actually i say that statement is 100% accurate. he didn't say it will. he said it can (it is easier). and they are different. being able to go from $0.01 to $0.05 is not the same as going up that much.
and it is in fact easier for a low-price altcoin to have that kind of rise than there is for a high-price cryptocurrency to have that kind of big rise. you can look at shitcoins such as Ripple. it had a massive pump last year from $0.005 to $0.5 and that is because they are much easier to pump.
there was a coin (i forgot its name) at the bottom of the tables which was worth 0.003 satoshi and it was pumped to 30 satoshi in 2 weeks with a ridiculous high volume near the end (999,900%)
and as far as trading strategies go, this is a high risk strategy but it can also be profitable.
