Long term - Bitcoin and Ethereum. Both are perfect assets.
Short term - altcoins like Ripple, Cardano and IOTA that are good for trading and buying something.
I absolutely agree with you! But current situation make me disappointed in my short term coins. I am ready to wait for changing price of long term coins. But small oynes now bring losses.
Lose is normally comes to our investment and its normal.
We need to reduce the lose but we can not do investment without losing.
However, from losing we can learn more experience.
