yes, ADA is a good investment, because ADA in the top 10 on coinmarketcap, so that proves if ADA is still popular and the current ADA price is $0.284 while the ATH price is $3.09, so if you invest in ADA at this time and the market start to increase again (bullrun) in the near future, then of course you will get a lot of profit, because I'm sure if a bullrun occurs, then the price of ADA will reach its ATH price or even a new ATH.
On every cycle, here comes that different new ATH on which surpassing the previous ATH which it is something that we do able to see in the market and comparing it on other coins
specially on top ranking ones on which they do able to break out their previous ATH. So far even ETH hadnt been able to break its 2021 ATh on which means that on this upcoming
cycle then we might be able to see difference. Although there's no assurance that it would happen but at least we arent that blind nor not really that too innocent on how this
market behaves. So far ADA is still really that good, they are still making updates and possible upgrades or whatsoever, it wont really be standing on the top ranks
if it was that a shit project after all.
