Same here unable to open the link. Anyways, apart from Bitcoin and Ethereum, spike is not the basis to invest because somehow it is a misleading information. The best way to find a long term investment is to search, read and understand the whitepaper. Active community is a plus factor to consider the team is working hard to produce success at the end. Still not 100% guarantee the success due to unpredictable movement of market, but it is much better to search, read, understand the whitepaper, and team factors than impulsive investment.
