There a lot of most suitable coins for longterm investments bitcoins are ones with good and All other alts are bounded to them and their volatility affect the price of alts. For short investments, alts are more suitable though, because they have more chances to multiply their value considering the lower price per token.
Yes, at least in the top #10 will be a good coins to invest for long term. But as for short term, just like most members here, I also have some portfolio on it but just a few coins only. I'm not comfortable having lots of coins for my short term trading.
Long term=I don't venture out top 100 normally (unless a super promising project with rep) Ex ETH or BTC right now.
Short term=Anything that has value and that upcoming roadmap something is happening. Ex ETC right now.
Short is dont to short and long is dont too long, that is the way i do it.
I never do very short trading like 1 day or 2 days and i never did trading more than 6 months. This way i do because i think this is smarter when we can make round trade and gain more money but not very short because its very risky
Sound advice. But I also do trade for 1 or 2 days just for the heck of getting some experience on it. Long term for me is like 1 year. Short term, 1 day and as long as 3 months only, then I take my margin of profits or if I can hit is earlier, which ever comes first.
