Selling altcoin and making profit is possible only at certain time. Altcoin trading at the right time and with the profit investing in bitcoin is a right decision.
I sold some of my Ethereum and Monero and convert into bitcoin. I will buy them when the price is low.
Good on your profit making tactics. Keeping alts for the growth of bitcoin is now turned to one method of earning bitcoin through alts.
I sold my Ethereum too early. I sold most of them when the price was $1.5. I thought it was high then.
You still managed a good profit.
Think of what you have managed to make, rather than what you missed out on. It always helps.
