I don't agree with you on the ground that apart from Bitcoin all others are shitcoin. In as much as I strongly believe in Bitcoin I also do believe in coin like ethereum and I don't think it will right for anyone to refer to ethereum as a shitcoin. Although, you were not specific about ethereum.
Practically, you are right because today's market has an answer to this. There are many surge and the most are from the altcoins that we never believed to be called coins. Trading has made me to adopt a method that has potential to handle risk, I mean potential risk. Whenever I trade with altcoins, I usually pick my profit at 2-4%. This is how I possibly minimize my risk.
