For me it is just coins from the TOP 20 market cap, from 2019 I am monthly still buying WAVES, Tron and LTC, in the long term big potential. When byu know then the price is low, nice profit in the next 5 years.
of the three coins you say I am more interested only in TRON if for a long-term investment, if we save the coin for the long term every month we will also be able to get some tokens from the results of the HF yesterday and that lasts for several years.
so you can imagine if the tron price is down but we can still get the tokens for our investment too.
Hardfork and this is my first time to hear about that and tron developer never announced before if they have a hardfork. Did you consider BTT as the hardfork from tron? you must try to learn more about that dude. you are missing a lot of important things about that.
