How to manage your funds:

First of all I will suggest not to go for futures, spot trading is ideal for everyone, where we can earn a lot futures is very risky you earn alot but you can lose everything, well In spot I suggest to invest 1000$ at least. After investing 1000$ divide your portfolio in 4 to 5 parts, invest in one or two coin from top ten of crypto like Bitcoin, Ethereum, Solana, XRP etc.

Now let's talk about our funds management.

You have 1000$ and let's suppose you want to invest in Polka dot and it's price is 4.5$

(1000/5= 200)

You can invest your 200 dollars at the price of 4.5$ of Dot

200/4.5= 44.44

You get 44.44 Dot by investing 200$ @ 4.5$ price

If market falls from 4.5 wait for at least 7 to 8 percent of market fall or place an advance order at 7 to 8 percent i.e

(4.5*8/100=0.36)

8 percent of 4.5 is 0.36 now place your other 200$ at 4.14$ of Dot

200/4.14=48.30 you will get 48.3 Dot now if market pumps @ 4.25 you can sell your 48.3 dot and will get profit easy and simple way

48.3*4.25= 205$ profit

But if market further falls you still have 600$ in your portfolio to buy dip till 24 to 25 percent more with 8%each.

I hope everyone understand, if not then you can ask and follow for further knowledge.
