Long-term cryptocurrency is better than day trading. Look at the statistics: almost all day traders lost a deposit, but scammers were able to increase their fortune tenfold
If someone keep investing their profits again and again into earlier capital after every trade then they have better chance of making more profits than long term traders but if you are making losses ad profits then your capital will go as the transaction fee so you will be in loss at the end with no benefits for doing such effort on your daily trading activities that is the reason why long term trading was suggested.
nothing is better, both are the same. in my opinion, it depends on your expertise in analyzing. if you want the long term, good to do on bitcoin because ultimately the price will continue to rise.
while altcoin is not so good for the long term. You can see the history of ATH prices on altcoin which is difficult to achieve again. while bitcoin will continue to make new history. So basically daily trading is good for those of you who rely on income from trading, while the long term is good for those who have a salary and keep it in bitcoin as a long term.
