no, i dont use the same percentages.. and I have never ever seen a base crack on ETH that didnt pay, so im not worried about any trade that I take on that coin.... There really isnt an exact science to the percentages, you are dealing with a ton of human traders, so every dip goes down a different amount, there is no way to predict the size of the panic drop you will get..

you have to guage the drop by the length of other drops in the past.. so if you are aproaching one of the deepest drops compared to all the others in the past 2 months or so, i would jump in heavy

EOS i want to hold longterm, but i dont have any right now, because of the situation (1year of dilution) but yes i keep a little of every trade as coins in profit and store them away.. i keep different amounts based on how much profit i made on the trade... if i made 20% on the trade, then i might keep 20% of the coins for the future..

Risk verses reward.. so if its very safe like ETH then my buys might be as big as 50% of my account.. if its less safe like AMP, then i might risk 2% of my account

Steem for sure LBC, UBQ, SNGLS, BLITZ.. those are a few of the ones ive taken alot of trades on lately

Time and Sales.. you just want to watch the tape and look at level two to see what is normal for the stock, you want to blend in with normal orderflow

I watch troll boxes if I am in a trade that dived for what traders might be saying..
