I think everyone also feels the same thing. When the year 2017-2018 there are still many successful altcoins. However, Altcoin has a high price when it is newly listed in Bursa and after that, the coin price starts to drop sharply. Some of my coins are also currently very low prices, but in the year 2018 have a decent selling value. Not all altcoins if on hold for the long haul, will have a high selling value.

If you want a long-term investment that has a good future is Bitcoin and Ethereum.
