Not all altcoin you can invest. You should choose the altcoin with the price fluctuation of the day with great changes. As I think you should choose altcoin like bitcoin, eth or altcoin in the top 100 on coinmarkepcap for you to invest.
I think that the chance to lose money increases because these coins are not so well known and it have much less chance of rapid growth.
What coins do you think? in fact, the coin mentioned earlier is a coin that has been inhabited and has a large transaction volume.
coins that are already in CMC are good coins, though not all, but if you are already above 100, you can be sure that the coins are quite good and safe for investment because they are already owned and owned by many people
