-trade for small profits. 3% earning on a transaction is good. Make that 79 times and you just have 10 times more money.
-small orders. Split your investment on at least 10 coins, put small orders, they will get executed a lot faster than bigger ones.
this was a good advice, I just disagree with these two.
small profit:
this is a good suggestion if you are already in with a big amount of money. you take 3-5% profit and enjoy it. but when you invest a small amount like $25 then 3% is $0.75 and that is lower than transaction fees.
also while trading altcoins it is possible to go bigger most of the times.
splitting orders:
the same reason. when you invest $25 splitting it is going to be hard. investing in 10 coins means $2.5 each and the orders sometimes can go even lower than the allowed order size.
I say it is best to invest in 1 specially if you are a beginner in trading. learn how things work. possibly even lose some money and after a while start making profit then increase the investment then go big.
it is all step by step. going big and investing in 10 different coins is going to be a headache to keep up with all of them as a beginner.
