i decide to sell my altcoins. when i noticed that i have a good and high profit to me. when i realized that the value of my altcoins doesnt rise high more. and lastly i decide to sell my altcoins when i really needed money. even if it low or high when i need it then i sell it.
your step is very precise, you must sell altcoin when it is good price and is in need. holding the coins too long is also not good because at any time the price of coins can drop drastically so when the price has reached the highest point better sold.
You have rightly said. Holding the Bitcoin for quite a longer time can result in loss but it can also result in having a lot of profit as well. I think if you want to play a safe game, then better is not to go for long term holding. You need to have something in your mind that you will sell you Bitcoins when this much profit Ill be getting.
