I think old project will be the best investment for you and you will never be disappointed with those projects because the best tokens always guarantee investors. Also if you want to hold for longer then definitely buy early top coins. If there are any profitable services offered by them, participate in them.
What a silly lazy answer. Yes since 2016, it is well known that the best tokens remain the best tokens during the next bullmarket (lmao)). When I see the number of people who want to invest in altcoins who have already made x100/200, it scares me. How many losses are they going to have to take before they realize that seed investors, VCs, or early investors are selling them on the face? You must never stop looking for new altcoins and looking for new narratives to achieve an excellent bullmarket and outperform the crypto market. It is not by comfortably but painfully holding old cryptos that have wrung out their speculative potential that you will make money. You can make money in cryptos but for that you have to work constantly and not sit idly by waiting for money.
