Actually 10k$ as a investment is a very good idea.You will get a more profit from it. With my calculation you can earn maximum of 1000$ per month as a profit alone.But you should analysis the market very well to shine over it.After analysis, you should make a decision about the investment. Once finalised, don't change your mind.Do trading with your own knowledge.
Could you please help me understand what calculations made you suggest that $1k is the maximum possible profit with $10k investment? Like OP said if one plays only with the BTC price movement, then he would have easily made a lot more and if someone is trading altcoins there is actually no limit how much one can earn and lose.
You will benefit when you just do on BTC/USDT that is without a doubt. This is now acceptable than losing your cash on Leverage exchanging. I will say that with a generally safe technique and utilizing no influence procuring 30% each year is conceivable with bitcoin, and in the event that you show restraint this is all that anyone could need to make you rich over the long haul.
Leverage trading was made for people who want to try their hands at trading but starting with small capital although want to trade big, so they take money on leverage and start their trading and see if they can survive.
Someone who has enough funds should never even think of leverage trading. The term "leverage" sounds good but its basically borrowing money by putting your assets on collateral.
