Altcoin is hard to speculate know why? because they are full of shit , most of them are scammer and most have no future at all.
It's not completely bullshit but indeed the average altcoin project now has no future and just follows the trend of hype, for example, meme coins that take advantage of prices that go up once and then fall deeper and that's what's hard to speculate.If it's an old project and it can stay at the top of Coinmarketcap then we can see their development and of course this speculation can be done on projects with their goals and products.
there are altcoin that already brings me profit from the past, but at least those are the coins that still in the top list lol.
But let us speculate using our risking funds and not our most saved funding .
