Comparison between an older coin 'Litecoin' and a newer one 'IOTA' Degeneracy can be observed in both cases Litecoin staged a reversal once this degen was finished IOTA i believe is in that stage as of current This isn't just tied to the crypto market it also occurs in other markets i have observed. However it is quite prominent in the crypto space.
Out of these two i would still recommend investing in LTC, due to its maturity compared to IOTA, and proven resilience.
Time and your own actions are the only variables if you decide to invest in these types of coins.
