I'm happy for you. Most altcoins for me also are just for hype. I already experienced this before during the early days of my experience in cryptocurrency.
I regret too much before because instead, I kept my Bitcoin, I exchanged them for some altcoins.
Another thing why there are some people are being lured to buy altcoins instead of Bitcoin is because of the ROI they can see versus Bitcoin.
This all comes down to risk and how much more risky you can be in such a situation when you have several options. Bitcoin has already shown to be a low-risk investment with a guaranteed return if you don't panic and buy and hold for a long time.
While most altcoins quit the market in the long run, the higher ROI they receive from some of these coins entice buyers to invest in them, despite the considerable high risk involved. Those that invest in altcoins are just picking between risky investments and those that will benefit them more even if things do not go as planned. But the big deal to invest in is still bitcoin.
