There is no problem with what you are trying to do, but please understand that trading is actually quite hard, otherwise everyone would do it.
I think there is a huge sell out pressure right now, because someone, or more likely a group of people with a lot of coins, are timing their sell outs to keep the price down, or maybe to create some panic and then buy at a smaller price. There is nothing you can do about it, and it's hard to beat them, because if we have very thin and unregulated markets, so it's easy for those guys to manipulate it.
Another option is to do nothing, and just wait. Put all your coins into bitcoin or ethereum, and forget about price movements. Development is happening, so with it, will come adoption. Once that happens the market will no longer be manipulated.
