BW-L21 Review – Litecoin (Scrypt) ASIC Miner

Picture copyright (c)

Most of us have given up on mining Litecoin since its price wasn’t enough to justify the electricity costs. Whoever kept mining LTC did that in the hope for the coin price to surge once again someday and they were not disappointed. While in January, the coin was valued at only $4 USD, its price surged 20 times in the past 9 months and it is priced $74 today, September 1.

Today we are witnessing Litecoin price peak and experts believe that it is very possible for Litecoin price to rise further and hit the $100 USD mark somewhere in the near future. While no one knows when exactly Litecoin will do that, it is obvious that now is the right time to mine LTC.

Where to Buy!


In Conclusion

It is needless to say that if small miners like you and me would like to enjoy mining with a BW-L21 Litecoin Miner, we would have to do a group purchase. Talking about which, community members are eventually gathering for one in this thread.

The miner hashrate looks really good, especially considering that Litecoin price might remain above the $70 USD mark for a while. Even if it dips once again, Litecoin is a valuable cryptocurrency and it is not going anywhere, at least while it keeps staying one step ahead of Bitcoin technology-wise.

That being said, some people do not like the way Litecoin is the “testbed for Bitcoin development”. At the end of the day, it all comes to personal preferences and trust.
