You should avoid altcoins with futires. I did the same with Notcoin some days ago and it didn't end well. I long at 0.23 and it's trading below that and I just had to close the trade with the losses.
If you just sticked to spot, you're probably gonna have some good profits. With coins like notcoin, while they're on the first lane you should maximize the chance of taking profit and don't ignore it when you do.
These are what I learn. Don't do futures with a coin that has a total trading than it's market cap, that means that the top is in.
Or much better not to do it when you're not focused on it.
Don't do a future with a coin that is too volatile, it will be in your favour when it's goes with your trade but the opposite is very brutal and you wouldn't like the outcome. Don't do futures with volatile markets.
Every coin is volatile and that's why you can't check them at all times and it's just best to stick with spot to avoid being liquidated.
