Yes if you have no bills to pay and grow your own food

It all depends on how successful you are at day trading. You can't rely on long term hodls if you need it to pay for your daily life otherwise you might be in for a spot of trouble during the next dump. The market always pumps and dumps, best to just bag some cheap alts now while you can
Highly agree with you we can't rely on btc or altcoins for daily life.Crypto market are so volatile and unpredictable and tho it's true that you can earn huge amount in trading but for assurance of your daily expenses montly bills and other extra cullicular activities you need a monthly income.
But it will always you(topic author) who can make a best decision and what will you profit more.
