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.
This is true that the higher the capital the higher the profit that you can get from your investment, but it is not always depend on the capital it is also depend on the strategy, because there are also investors that earn big even if they only have a small amount of capital specially on crypto investment because they took advantage with the high volatility network, and there are also high capital investment that never earn because they don't hold and sell at loss when the market is dumping.
