first and foremost, no one here has the crystal ball to tell the OP if those coins will still be here after 5 years. what he will get here is just pure speculations. for him to assure that his coins are worth holding long-term, he needs to follow the developments of each one and assess if they are doing any progress. because if he feels there's nothing happening on the project, better discard and move on to the next one. don't wait too long because as he waited the value will continue to decline for most dying projects.
the projects mentioned are promising but it is on you how you will keep up with them
well, nobody has a crystal ball, so we can only speculate on this.
only, he mentions coins that are popular and have a high need and demand from the past until now. for that reason, there is a high chance that the coin mentioned will still be around, either the demand is decreasing, or the price will be higher. However, this is still speculation. If he doesn't feel that the coin will last, selling it when the feeling comes will make him feel better. I believe because it's a popular coin, it's different if it's a new altcoin
