Will there be another "dot com" bubble? What should you do with your investments in that situation?

1. Keep invested, NEVER sell your assets just because of fear. We can't predict the market in the short term, but market is super predictable in the long term (10 years). There is only one direction, up (in most cases).

2. Continue to DCA every month/ quarter/ year. Depending on your financial situation, if you are tight on cash during crisis, then stop investing for some time after you have build up enough to cushion you through the crisis in addition to some spare cash, only then you resume your DCA.

3. Have a watchlist of the stocks that you would like to buy at discount. Crisis always present us with the most fantastic opportunities to buy our favourite companies at discount, do have your warchest ready and prepare to go for a shopping spree.

Besides US tech stock, alternate crypto coins is also bubbling now!

The best way to solve that situation is not to be in that situaton in the first place.

There are always markers to a bubble. Such as over-optimism or overhyped of a growth story and pretty clear overvaluation in a particular stock.

So the best thing to do when you see ridiculously priced assets or stocks is that you should get out.

Yes.

Human nature to have bubbles.

Buy more when it happens.
