There's absolutely no difference based on the amount you're trading other than the fact that more money means more risk and more difficulty getting in and out of trades.
Let's say you and I use exactly the same trading moves, and we are equally successful - over the same period of time you would earn 10 BTC and I would earn 1 BTC. How can that be the same?
Although, I do agree that risk is higher for you, but if you care about difficulty of getting in and out, you will invest in coins with higher price and volume. Just as I will invest in coins with lower price and can easily get out on lower volume.
Now, I'll also choose different entry and exit points - aaaand there you go - we are already doing different things because it's only natural.
Ok, it was nice exchanging opinions with you, but I assume we shouldn't spam Start thread any more.
Sorry guys about the spam, good luck to you all.
