Maybe there's something you are not doing right. 125x is so huge. Just an 1% price change in the right direction from your open position means 125% increase in profit. I don't recommend it because chances of getting your whole position liquidated are very high.
Those altcoins you have listed, how many of them have turned $5,000 into $500K? Do you know how many have turned dumped by over 90% in the bear market?
I am not sure this is true. I was long on Bitcoin with x125 and it went up by like $1000 so thats already more than 1%. Its like 3%. And I think I made like 100% or even less actually.
I only use isolated so i assume when you dont use isolated and you bet a lot more of your capital (which i dont find very smart), you could make more?
Also you can set a stop-loss so your position wont get liquidated like if you think Bitcoin (or ETH, Doge, whatever) will go up I dont see why you would NOT use x125 (well, x25 max with Doge), I mean with stop-loss you could still minimize your losses to like 10% or 25% in case it goes down.
But yeah I am new to this so i appreciate any tips.
As for the price I go long/short on i always try to use the max price I can put in (it wont let me put $41k on bitcoin for example) so i am not sure if that makes a difference. Lets say I bet on bitcoin being $500 higher i still make a bigger profit when it goes $1000 higher right? so i am not sure if it makes a difference if i bet on +500$ or on +$1000 of current price?
As for the other question, yes I made x50 or even more on a lot of projects. But its true some went down 95% (like eth lol) or even more actually
But I see this as inspirationto find better projects next time. Like currently I really, really like KoinOS. Its so cheap i dont see how it wont go up in the long run and so you probably would make a lot more money even day trading it, or just holding it for a long time. Because no matter if its 2,3 or 5 cents now, its still very cheap. I mean even at 10 cent. So that seems the better and safer strategy than using x125
