hallo friend, how about bitcoin, ethereum, coindash, and monetha? bitcoin and ethereum I think is suitable for long term or short term. coindash and monetha suitable for long term. i heard coindash and monetha will pump the price in 2018.
i agree about bitcoin because i already tested it and both actually works on short term and long term whether it is an investment or for trading. some altcoins like etherium and others that you mention are mainly works for a longer term based on my own observations its because they tend to increase slowly but surely and also most of them are quite stable just like etherium which is good to hold if your looking for a lesser risk investment and to earn a stable profit at the same time.
Due diligence is fundamental in the choice of the coin to invest your money in. There is no suggestion to make or say names of coins you might buy for both short or longer term. You might get just more confused. Nevertheless, you already know which is your pick(s).
yeah i also agree with this. @op overall you should the one who make your own research and to decide which coin suites you the most because there were time that others strategy might work for them but might not work for you, so youd better go on your own to avoid blaming others if all fails. just always remember the golden rule which is
never invest on what you can afford to loose. goodluck
