Nothing wrong with that although none of those coins have much room for huge returns, perhaps this is the risk level you prefer.
Tron I feel is just as likely to go down in value vs go up, and if it does go up it won't be a huge multiplier.
What sort of returns are you expecting and do you have a period of time in mind?
I bought the most coins for holding long term ( min. 1 year ) but as you mentioned above with tron, I try to et rid of them as soon as it hits 0,1 again. Read through many opninions here and I guess I will let go my LTC as soon as its gets also a bit higher. I will try to diversify a bit more in small coins which yield great growth potential. Not quite sure which ones to pick here but at the moment I'm reading into Lamden (TAU) and doing some research. I was also thinking of putting even more in XRB, I really believe in raiblocks (nano soon) and feel comfortable with the idea of holdig more of it.
Like CalRon said, LTC is a good coin to hold. Not massive gains but very stable.
Increase your VEN holding, get some ICX & ELF, discard TRON.
Waiting for TRON to recover may be bad...because it may never and the coin you are buying to replace it with may spike up. At least now you are selling it at a discount but you are also buying another coin at a discount.
