From basic economic principles, if you have a higher capital, you will certainly have higher returns compared to starting with a smaller capital. If you're just chasing returns or expecting a huge profit margin but pay slight attention to how much you use as your capital, even when you make a profit, the extent of your profit will largely depend on how much is your Capital.
REMEMBER
50% profit on $1000 is $500
5% profit on $100,000 is $5000
THE IMPLICATION IS;
Don't chase bigger returns, chase more capital. This is also applicable to How much you invest in Bitcoin and how much profit you can get from it.
