The best advice, buy with several stages. This I also do in trading.
Only if they have doubts about the lump sum, Only if they are unsure about the lump sum, then they can consider the DCA.
But the first piece of advice I give is to choose the best altcoins. The best here may be a little difficult, but for sure there are some coins that have been able to survive to date and thrive instead of the hype.
It would be better if you could recommend it instead of just saying. I did not analyze altcoin, but basically altcoin can also be considered as an investment
[only investment, not use cases].Indeed, no one knows when the price will fall, but a trader must know that there is an analysis that must be used. Technical analysis that many traders already know and agree on. Well at least that can help,although in the end the market may change because of the owners of large funds(whales).
Prices can move in any direction either up or down. Demand and supply will affect it and these fluctuations are really hard to predict. You are safe if you invest an amount you can afford to lose, while you also need to adjust your budget for other needs.
