Who can explain me? Why any Issuer can easy increase number of shares?

It had 2 type of issuers.

First type. Look for example in history data:
1. https://btct.co/security/ACTIVEMINING 2924534->3069481->3071989->3074084, Outstanding 3074084 / 25000000 Issued.
2. https://btct.co/security/BASIC-MINING ...50000->51625, Outstanding 51625 / 1000000 Issued.
3. and other...

How I understand market cap of ACTIVEMINING is 0.005497*25000000 = 137425 BTC, it's looking huge.
Or BASIC-MINING is 0.149*1000000 = 149000 BTC, it's actualy huge for 1435 Gh or 103 per 1 Gh.

It's ability give issuer to sell evrytime and price can fall 200 times as BASIC-MINING until normal gigahash price.

Second type a bit worse.

1. https://btct.co/security/COGNITIVE 8619->9032->8619>8620->8629->8809->9709->10420, Outstanding 10420 / 10420 Issued.

This issuer just change Details in Contract & Prospectus and drop new shares into market.
Issuer made it without preffered offer to old shareholder by special price. Is it correct?

May be BTC-TC is big scum? Explain me please!

And sorry for my english.
