Most of my altcoins are bought through investment. I feel that although I can get a lot of money by relying on airdrops, there are a lot of coins in airdrops. I think it is a waste of time to fill in the airdrops.
airdrops are good but i would not trust them a lot though investment is another issue and here i am quite interested
investment is great i agree especially a l9ng term one but i would not be so strict about airdrops they can be good as well
