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.
Now
*Hold
*Sell
*Trade
Looking forward to the opinion of the experienced.
It depends on what altcoin you are investing in, if the altcoin is not popular and doesn't have strong fundamentals maybe in my opinion it is better to sell it immediately when there is an increase in the price of the coin so that by selling it at least all your funds are not lost because basically almost all altcoins are not the right choice for us to hold in the long term, most of them are only suitable for us to make as an alternative if our funds are not enough to buy bitcoin, holding altcoins in the long term other than ETH and BNB is very risky, only two of these altcoins that we can trust and have proven to be able to survive all this time .
