Maybe if I choose both. For the long term then the main one is buying Bitcoin do not an altcoin.
And for day trading try that has good daily trading in the market. So we not only wait for the long profit but we also get profit every day.
Or try to switch investments to IEO which can get a pretty fast profit.
There's no maybe here, we are free to do both of them if we can and if we want to. Long term holding is not complicated, you invest in coins you like and keep them in the wallet, when ever you wish to add more you can do it buy buying more coins and transfering them to wallet, simple and easy, doesn't take much time.
Short term trading on other side can be a full time job, to do it everyday for hours if you want. You can use multiple exchanges, some way to track all of your trades, all in all it can be exhausting.
Some are capable for doing both, and who is capable should practice both.
Of course, we can choose both if we are able and have much more time to do daily trading. But for people workers can only make long-term investments because they are too busy with other jobs. Both can be done if we are unemployed.
