In my opinion some coin that could be safe for trading is coin that has good fundamental and the volume is high like ETH, DASH, WAVES, LTC, NEO, XMR, NEM. Because if the price down from the price that you bought so still any posibility the price will going up later, just patient to wait for that.
Your list is quite good and most of them I'm having already. But OP got only 0.05 BTC to invest so I think it is good to put only in two coins instead of so many coins. I think NEO and ETH may be a good option to try. This is just my suggestion but OP needs to study the coins and make a final decision which to invest or just hold BTC, in the long run, it will give a good profit.
That's right, but in the concept of being safe, I say that none of them are really and for certain safe. It's because that's just how the market works. There are so many changes happening that it can insight a number of negative scenarios that may affect the market for the worse together with its assets. However, on the one hand, it can also bring about positive changes that can help many coins rise up and recover what they lost, especially during the times when many of them are falling down in value. It's just how the market works; you have to embrace the fact that it will be risky and can be a reason for your investments to go down the drain, especially if you're not ready for it.
