Well, my goal was to make some money with the futures, and then I could invest in Btc or Eth and wait
I like the idea that you separated investment from trading. Best form of trading is just the futures you mentioned above. Aitcoins and bitcoin are both use for future trading, but due to volatility rate of most Altcoins which is way higher than bitcoin, they tend to have better returns on future but same as risk in a short period of time. My advice is if you’re not that sufficiently knowledgeable to future trade, then just leave your funds only on investing rather than risking the smaller investment again on future trading
despite that risk is something that come out positively sometime it is good for someone to take a risk but you should take a risk for something that you know better not something that you don't know the beginning or the end so it is also better for someone to hold a bitcoin for long time or hold your hot coin for long time down investing on something that you don't know or trading for something that you don't know
