Most people who are proudly calling themselves traders are not like that. They would be just waiting out the bad times till the price rebounds. and they are able sell at a profit. With Bitcoin, it usually works out just fine at the end of the day (unless you bought your bitcoins in late 2013 at over $1,000 per coin, of course), but with altcoins that might be and most likely is fatal, given that the total majority of these "coins" are outright scams...
Which all without exception eventually end up at 1 satoshi
It has different market so you will be tested if you can succeed or not.
I have a strong inclination to think that making money through scam coins has nothing to do with your trading skills as such. You either make money there simply because you belong to the group which is pushing that coin to the market (and which can be loosely called as "scammers") or just turn out to be exceptionally lucky to both get in just in time and get out just in time. So, there is no real reason to get yourself tested whether you can succeed in that market or not...
You can just play the Russian roulette instead
If one trader is exposed to lots of scamcoins or shitcoins, they are able to tell the movement of the coin. This is what we know as experience. With this they can be able to earn profit from the said coins even if they have no affiliation to those scam devs. I don't believe its luck though.
And technical analysis can't say anything for that.
