Honestly, I participate in investing for profit, but consider technology as a criterion to choose what is a good investment for me. With Bitcoin, there is no need to consider, technological factors may not need to be considered, but with ALtcoin it is a different story. You must consider technological factors to choose which Altcoin is worth investing in, and which technology will lead the story for the next bull cycle. There are many Altcoins whose technology is no longer suitable for the next growth cycle, such as anonymous ALtcoins like Dash, Monero... Honestly, when investing in Bitcoin, my mentality is extremely comfortable, don't have to worry much, even though sometimes Bitcoin has large corrections of 20-30%, but I'm still confident the price will soon recover and grow again. However, with ALtcoin there is another story, always has a certain amount of anxiety when investing. Therefore, my investment portfolio always prioritizes the majority of the portfolio for Bitcoin, only a few for Altcoins.
