In my personal opinion, selling all your Bitcoin to buy into altcoins isn't a sound strategy. If you had held onto your Bitcoin for five years instead of LTC, the potential returns might have been greater. Bitcoin's long-term potential is widely recognized, and many investors believe in its long-term growth. While LTC has its merits, banking solely on it for long-term gains may not be prudent, especially considering the evolution of other coins that have outpaced its original purpose. While you've made profits, I'd recommend prioritizing Bitcoin for long-term investments and exploring altcoins for shorter to mid-term opportunities.
