My opinion, Bitcoin all time saving mode is the best way. Some time when bitcoin price up then sell and when price down then buy is the best decision. This method all time not working for trade. Many time i noticed when i sell bitcoin or altcoin sell since then price grow up and up. And when I buy bitcoin or altcoin then price low day by day. specialy, altcoin hold, sell and trade big loss. 4 years ago few coins i hold for future. now this coin price few value or most of coin value is zero. Few coin trade, there too big loss. past year in the case of 1 coin invest $1000, this coin price today zero
I guess holding Bitcoin for the long term is the best deal, and holding altcoins for the long term is a little bit too risky since not a lot of altcoins survive the bear market and not many of them rise to the ATH just like before the bear market. I guess trading Altcoin is better for people who want to earn big profits but with big risks too.
Most of the altcoins are indeed very volatile, and risky to hold in the long term, only a few altcoins may be safe for long term investment. it would actually be easier to invest than to trade, let alone bitcoin. for those who are already proficient at trading, of course there is no obstacle to doing both, but for many speculators who are looking for new altcoins to invest in, until the price soars and sells them
